I tried to post this direct to the requester, but my mail came back D.O.A. It is possible to have two adjacent edge cubes flipped and interchanged on Rubik's Revenge. It is also possible to have two adjacent corner cubes flipped and interchanged. Both of these phenomena are acheived by having corresponding center cubes cycled. In answer to other queries about N^3 cubes (N>=5). Yes, solving these are interesting, but after N=5, the problem is trivial. N=5 introduces one 'new' situation (which is really a variant of the adjacent edge interchange). After finding this solution, the solution of an N^3 cube simply requires time, sweat, and the application of known algorithms. (The above information was research as part of a Summer NSERC grant). Now, a question of my own. Has anyone actually seen a working N^3 cube for N>=5? If so, can you tell me where they may be purchased? G.H.A.
