DESCRIPTION

       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  (http://www.mefferts-puzzles.com). 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).

FEATURES

       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 "R" or "r" keys to randomize  (this  must
       be done first to set a new record).

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

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

       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  "facets",  if  at  all  (i.e.
       those  "facets"  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 "S" or "s" keys to  start  auto-solver.   Only  works  on  1x1x1,
       2x2x2, and 3x3x3 pyrmaminxs in Period 3 mode.

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

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

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

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

       Press "Esc" key to hide program.

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

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

         8 9   Up, Upper Right
         ^
       4<5>6   Left, Clockwise, Right
         v
       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 "facets" 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
       noaccess".

OPTIONS

       -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.

       -[no]mono
               This option allows you to  display on  a  color  screen  as  if
               monochrome (resource name "mono").

       -[no]{reverse|rv}
               This  option  allows  you to see the pyraminx window in reverse
               video (resource name "reverse").

       -{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").

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

       -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
               cheating.

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

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

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

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

       -[no]orient
               This option allows you to access the orient mode (resource name
               "orient").

       -[no]practice
               This  option  allows  you to access the practice mode (resource
               name "practice").

       -delay msecs
               This option specifies the number of milliseconds  it  takes  to
               move  a  tile  or  a  group  of  tiles one space (resource name
               "delay").

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

       -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.

       -version
               This option tells you what version of xpyraminx you have.

RECORDS

       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  auto-
       solve.

SAVE FORMAT

       The format is not standard.  The reason for this is that this is simple
       to produce and the standard notation is no good for variable number  of
       "facets" 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 "facets" to  be
              oriented>
              sticky:  0-1  <0  false,  1  true;  if 1 then some "facets" move
              together>
              practice: 0-1 <0 false, 1 true>
              moves: 0-MAXINT <total number of moves>

              startingPosition: <2 dimensional array of face "facet" position,
              each  face  has  size  *  size  "facets",  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  "facets"  (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.
