Rubik's Cube (a mechanical puzzle aslo called the "Magic Cube") has
always been a favourite for puzzle solvers. Many use the methodology
of alogorithm (sequenced moves) like the very easy " F2U'R'LF2RL'U'F2
" to solve the puzzle.. but here is now an automated method.

Enjoy!!
Wow that's neat.
I see it was recently proved that any cube configuration is at most
26 moves from any other (in the same one of the 12 possible disjoint
orbits obtained by dismantling and reassembling the cube).
Anyone know if this upper bound is sharp. If not, I'd conjecture
that the LUB is 24.
