       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 solv-
       ing 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).


       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 "R" or "r" keys to read a saved puzzle.

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

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

       Press "E" or "e" keys to redo a move.

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

       "S"  or "s" keys to start auto-solver.  Only works on 1x1x1, 2x2x2, and
       3x3x3 facets in Period 4 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  "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  dis-
       abled 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.

       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 Oct as:
         /     Counterclockwise

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

       Use the shift keys to access "Period 4" turns from "Both" mode,  other-
       wise  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

       -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.

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

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

       -{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").

       -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

       -{border|bd} color
               This option specifies the border color  of  the  octas  in  the
               octahedron 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 octas 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 3
               and period 4 (resource name "mode" set at 5).

               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 xoct 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

       Each turn is with respect to a face and position.

       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
       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.
