Date: 17 JUL 1980 1420-EDT From: RP at MIT-MC (Richard Pavelle) Subject: the cross design To: CUBE-LOVERS at MIT-MC Does anyone know a transformation (or series of) which will produce the following pattern on each face where X and O are two different colors. |X O X| |O O O| |X O X| I think this may not be possible which brings me the question which is how one can say whether a particular arrangement is or is not possible.
