       The original puzzle has 9 triangles per face (size = 3) and has  period
       3  turning (i.e. the face or points turn in 120 degree intervals).  The
       puzzle was designed by Uwe Meffert and called the Pyraminx.   This  has
       2^5*3^8*6!/2 or 75,582,720 different combinations.

       Another  puzzle  Senior  Pyraminx  3x3x3  exists  only on paper, it has
       period 2 turning (i.e.  edges turn with 180 degree intervals)  but  the
       corners  would fall off unless it had some tricky mechanism.  (This may
       be the same  as  the  Master  Pyraminx  which  has  446,965,972,992,000
       different combinations).

       Another  puzzle (which was not widely distributed), the Junior Pyraminx
       (and similarly the Junior Pyraminx Star, a  octahedron  formed  by  two
       tetrahedra, this has 7!*3^6 or 3,674,160 different combinations), has 4
       triangles (size = 2) per face.  This puzzle has been recently  reissued
       by  Meffert  as  Pyramorphix  ( At the
       time I designed this computer puzzle thought that it had only period  2
       turning (i.e the edges rotate).  It turns out the puzzle has a period 4
       turning (edges turn with 90 degree intervals) which makes it  analogous
       to  the  2x2x2 Rubik's cube.  This puzzle makes various non-tetrahedral
       shapes.  The puzzle contained here has no period 4 turning flexability.

       One is able to simulate Halpern's Tetrahedron or  Pyraminx  Tetrahedron
       (period  3 turning and sticky mode).   Also one is able to simulate one
       with variant turning (period 2 turning and sticky mode).


       Press "mouse-left" button to move a piece.  Release "mouse-left" button
       on  a  piece  on the same face and in the same row (but not an adjacent
       piece or the move is ambiguous).  The pieces  will  then  turn  towards
       where the mouse button was released.

       Click  "mouse-center",  or press "P" or "p" keys to toggle the practice
       mode (in practice mode the record should say "practice").  This is good
       for learning moves and experimenting.

       Click  "mouse-right", or press "Z" or "z" keys, to randomize the puzzle
       (this must be done first to set a new record).

       Press "G" or "g" keys to get a saved puzzle.

       Press "W" or "w" keys to save (write) a puzzle.

       Press "U" or "u" keys to undo a move.

       Press "R" or "r" keys to redo a move.

       Press "C" or "c" keys to clear the puzzle.

       Press "S" or "s" keys to  start  auto-solver.   Only  works  on  1x1x1,
       2x2x2, and 3x3x3 facets in Period 3 mode.

       Press "O" or "o" keys to toggle the orient mode.  One has to orient the
       faces in orient mode, besides getting all the  faces  to  be  the  same
       color.   To do this one has to get the lines to be oriented in the same
       direction, this only matters with center pieces, if at all (i.e.  those
       pieces not on a corner or edge).  This does add complexity so there are
       2 sets of records.

       Press "2", "3", "B", or "b" keys (not the keypad 2, 3) to change  modes
       to Period 2, Period 3, or Both.

       Press  "Y"  or  "y"  keys  to  toggle sticky mode (increase/decrease is
       disabled here if sticky mode is on).
       "Sticky" and "Period 2" turning allows only the edges to turn, and  the
       2  center  rows  turn together. It is as if the middle cut of the three
       cuts did not exist.
       "Sticky" and "Period 3" turning allows only the faces to turn, it is as
       if the middle cut of the three cuts did not exist.
       Beware,  the  "Sticky" mode is a hack and much could be done to improve
       its look.

       Press "I" or "i" keys to increase the number of pieces.

       Press "D" or "d" keys to decrease the number of pieces.

       Press ">" or "." keys to speed up the movement of pieces.

       Press "<" or "," keys to slow down the movement of pieces.

       Press "@" key to toggle the sound.

       Press "Esc" key to hide program.

       Press "Q", "q", or "CTRL-C" keys to kill program.

       Use the key pad or arrow keys to move without the mouse.
       Key pad is defined for Pyraminx as:
         /     Counterclockwise

         8 9   Up, Upper Right
       4<5>6   Left, Clockwise, Right
       1 2     Lower Left, Down

       Use the shift keys  to  access  "Period  3"  turns  from  "Both"  mode,
       otherwise  it  assumes  "Period  2"  turning.  Faces and points turn in
       "Period 3" and edges (2 points) turn in "Period 2".

       Use the control key and the left mouse button, keypad, or arrow keys to
       move the whole tetrahedron.  This is not recorded as a turn.

       The title is in the following format (non-motif version):
              xpyraminx.{2|3|both<turning                             modes>}:
              {1|2|3|4|5|6|7|sticky<number of pieces per edge>} @ (<Number  of
              moves>/{<Record    number    of    moves>   <user   name>|"NEVER
              noaccess"|"practice"}) - <Comment>
       If there is no  record  of  the  current  puzzle,  it  displays  "NEVER


       -geometry {+|-}X{+|-}Y
               This  option  sets  the initial position of the pyraminx window
               (resource name "geometry").

       -display host:dpy
               This option specifies the X server to contact.

               This option allows you to display  the  pyraminx  window  on  a
               color screen as if it were monochrome (resource name "mono").

               This  option  allows  you to see the pyraminx window in reverse
               video (resource name "reverseVideo").

       -{foreground|fg} color
               This option specifies the foreground  of  the  pyraminx  window
               (resource name "foreground").

       -{background|bg} color
               This  option  specifies  the  background of the pyraminx window
               (resource name "background").

       -face{0|1|2|3} <color>
               This option allows you to change the color of a face  (resource
               name  "faceColorN").  In mono-mode, color is represented as the
               first letter of the color name. The faces are  ordered  top  to
               bottom  and  left  to  right.  If you has two colors that begin
               with the same letter you should have one in uppercase  and  one
               in  lowercase  to distinguish them in mono-mode. You can change
               the colors of the faces to make a  stupid  pyraminx  (i.e.  all
               White  or  in  mono-mode  all "W").  Unfortunately, it will not
               normally say its solved when its  randomized.   This  would  be

       -{border|bd} color
               This  option  specifies  the  border color of the pieces in the
               pyraminx window (resource name "borderColor").

       -delay msecs
               This option specifies the number of milliseconds  it  takes  to
               move pieces (1-50) (resource name "delay").

               This  option specifies if sliding pieces should make a sound or
               not (resource name "sound").

       -moveSound filename
               This option specifies the file  for  the  move  sound  for  the
               twisting of the puzzle (resource name "moveSound").

       -{font|fn} ontname
               This option specifies the font that will be used (resource name

       -size <int>
               This option allows you to change the number of pieces on a edge
               (resource name "size").

       -sticky This  option  allows  you to set the sticky mode (resource name

       -mode <int>
               This option allows you to set the turning mode  (resource  name

       -both   This option allows you to set the turning mode to both period 2
               and period 3 (resource name "mode" set at 4).

               This option allows you to access the orient mode (resource name

               This  option  allows  you to access the practice mode (resource
               name "practice").

       -userName string
               This option specifies the user name for  any  records  made  or
               else it will get your login name (resource name "userName").

       -scoreFile filename
               Specify an alternative score file (resource name "scoreFile").

       -scores This option lists all the recorded scores and then exits.

               This option tells you what version of xpyraminx you have.


       You  must  randomize  the  puzzle  before a record is set, otherwise an
       assumption of cheating is made if it  is  solved  after  a  get  or  an


       Here  is the format for the xpyraminx configuration, starting position,
       and the movement of its pieces.   The  format  is  not  standard.   The
       reason  for  this  is  that  this is simple to produce and the standard
       notation is not easily scalable  for  variable  number  of  pieces  and
       turning modes.

       Pyraminx with default colors, not randomized:
       0     B     Blue
         1     R   Red
       2     Y     Yellow
         3     G   Green

              size:  1-7  <number  of triangles in the same orientation as the
              face per row>
              mode: 2-4 <period 2 turning, period 3 turning, or both (4)>
              orient: 0-1 <0 false, 1 true; if 1 then lines on  pieces  to  be
              sticky:  0-1  <0  false,  1  true;  if  1  then some pieces move
              practice: 0-1 <0 false, 1 true>
              moves: 0-MAXINT <total number of moves>

              startingPosition: <2 dimensional array of face  piece  position,
              each   face  has  size  *  size  pieces,  if  orient  mode  then
              orientation number follows face number: 0 up, 1 upper  right,  2
              right, 3 down, 4 lower left, and 5 left>

       This is then followed by the moves, starting from 1.
              move #: <face> <position> <direction> <control>
       Each turn is with respect to a face and position.
       Position  is 0 to size * size - 1.  Position 0 is the triangle furthest
       from the center, increasing clockwise.
       Direction is represented 0 up, 1 upper right, 2 right, 3 down, 4  lower
       left, 5 left, 9 clockwise, and 15 counterclockwise.
       Control  is  represented as 0 or 1, 1 if the whole tetrahedron is moved
       at once (here position does not  matter),  0  if  not.   The  xpyraminx
       record keeper does not count a control move as a move, but here we do.

       If  you have a Pyraminx you can not solve (2x2x2 or 3x3x3), enter it in
       pyraminx.log file.  Have size = 2 or 3, mode = 3, orient = 0,  practice
       =  0,  randomized  = 1, and moves = 0 and the number representation for
       the color of the  pieces  (usually  0=B,  1=R,  2=Y,  3=G).   Bring  up
       xpyraminx,  hit  'g'  so it will get your configuration and then 's' to
       solve your pyraminx and then 'w' to write out the steps.  Then  examine
       your pyraminx.log file.
