I suspect 4x4x4 might be harder than 5x5x5 because there would be \no/ fixed pieces (in the 3x3x3 cube the center cubies are mounted on a common centerpiece; each can spin freely but not change its orientation with respect to the other center faces. This is why you can exchange 4 centers with their opposites but not all 6.) I also suspect that a 5x5x5 would be fragile and temperamental--- but it would make a cute problem. (Note: the SCIENTIFIC AMERICAN cover article stated that a number of smaller cubes and even some small non-cubes (2x3x3 or 2x2x3?) had been made.) ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
