# Independently rotating cubelets of a 2 x 2 rubiks cube?

I was reading up on 2 x 2 Rubik's cube. Wikipedia says that

Any permutation of the eight corners is possible (8! positions), and seven of them can be independently rotated (37 positions).

• Instead of 37 positions I believe you mean $3^7$ positions? – timidpueo Apr 9 '14 at 20:40
