DESCRIPTION

       The  original puzzle has 9 triangles per face (size = 3) and has period
       4 turning (i.e. the face or points turn with 90 degree intervals).  The
       puzzle  was designed by Uwe Meffert and called the Magic Octahedron (or
       Star Puzzler).  The puzzle was not widely distributed but  not  exactly
       rare.   This  puzzle  has  some  analogies  to the Rubik’s Cube and the
       solving techniques are the same to that of the  Pyraminx.   Christoph’s
       Magic  Jewel  is  similar except there are no trivial corners to solve.
       This has 2^22*12! or 2,009,078,326,886,400 different combinations.

       Uwe Meffert also noticed that there could be an alternate twisting  for
       the  octahedron where it has period 3 turning (i.e. faces turn with 120
       degree intervals).

       One is able to simulate a Trajber’s Octahedron (period  3  turning  and
       sticky  mode).   Also  one is able to simulate one with variant turning
       (period 4 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 "octas".

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

       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  "octas", if at all (i.e.
       those "octas" not on a corner or edge).  This does  add  complexity  so
       there are 2 sets of records.

       Press  "3", "4", "B", or "b" keys (not the keypad 3, 4) to change modes
       to Period 3, Period 4, or Both.

       Press "Y" or "y" keys  to  toggle  sticky  mode  (increase/decrease  is
       disabled here if sticky mode is on).
       "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.
       "Sticky" and "Period 4" turning allows only the points 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.

       "S" or "s" keys reserved for the auto-solver (not implemented).

       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 Oct as:
         /     Counterclockwise

       7 8 9   Upper Left, Up, Upper Right
         ^
       4<5>6   Left, Clockwise, Right
         v
       1 2 3   Lower Left, Down, Lower Right

       Use  the  shift  keys  to  access  "Period  4"  turns from "Both" mode,
       otherwise it assumes "Period 3" turning.  Points turn in "Period 4" and
       faces turn in "Period 3".

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

       The title is in the following format (non-motif version):
              xoct.{3|4|both<turning  modes>}:  {1|2|3|4|5|6|sticky<number  of
              "octas"  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 octahedron 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 octahedron window in reverse
               video (resource name "reverse").

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

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

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

       -face{0|1|2|3|4|5|6|7} <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 octahedron (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 octas 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 3
               and period 4 (resource name "mode" set at 5).

       -[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").

       -{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 xoct 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.

SAVE FORMAT

       The format is not standard.  The reason for this is that this is simple
       and I do not know what the standard is.

       Octahedron with default colors, not randomized:
         0       R     Red
       3   1   M   B   Magenta, Blue
         2       W     White
         4       O     Orange
       7   5   Y   P   Yellow, Pink
         6       G     Green

              size:  1-6  <number  of triangles in the same orientation as the
              face per row>
              mode: 3-5 <period 3 turning, period 4 turning, or both (5)>
              orient: 0-1 <0 false, 1 true; if 1 then lines on "octas"  to  be
              oriented>
              sticky:  0-1  <0  false,  1  true;  if  1 then some "octas" move
              together>
              practice: 0-1 <0 false, 1 true>
              moves: 0-MAXINT <total number of moves>

              startingPosition: <2 dimensional array of face "octa"  position,
              each  face  has  size  *  size  "octas",  if  orient  mode  then
              orientation number follows face number numbered clockwise from 0
              to 11, where 0 is up>

       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 as 0 up, 1  upper  right,  2  right,  3  lower
       right,  4 down, 5 lower left, 6 left, 7 upper left, 9 clockwise, and 15
       counterclockwise.
       Control is represented as 0 or 1, 1 if the whole octahedron is moved at
       once (here position does not matter), 0 if not.  The xoct record keeper
       does not count a control move as a move, but here we do.
