This is the number of positions that can be reached in n moves from the start, but which cannot be reached in fewer than n moves.

A puzzle in the Rubik cube family. The total number of distinct positions is 100776960.

The single position at maximal distance from the start is the superflip, the position with all six faces flipped but otherwise correct.
