Question

Suppose you take a Rubik's Cube and label all the edge squares with numbers as in the diagram. (It doesn't really matter what order you label them in, just so each square has a different number.) There should be 24 labeled squares in all (you can only see 12 of them in the diagram; the rest are on faces you can't see.) Then when you turn the various sides of the cube, you permute the set of numbers {1,2,...,24). We're completely ignoring the motions of the corner squares on the Cube. 10 12
