Permutations The original (333) Rubik's Cube

has eight corners and twelve edges.

There are 8! (40,320) ways to arrange the corner

cubes. There are 12!/2 (239,500,800) ways

to arrange the edges. There are exactly

43,252,003,274,489,856,000 permutations, which

is approximately forty-three quintillion. The

preceding figure is limited to permutations that

can be reached solely by turning the sides of

the cube. If one considers permutations reached

through disassembly of the cube, the number

becomes twelve times as large The full number

is 519,024,039,293,878,272,000 or 519

quintillion possible arrangements of the

pieces that make up the Cube. -http//en.wikipedia
