Just as well, you'd have been disappointed. As I wrote on 8 Jan 92,

: While most people are content to make each face a solid color, some

: with respect to the rest of the cube.
: [This has recently been done commercially in an spectacularly
: braindamaged way, in a product known as ``Rubik's cube--the

: only four face centers, breaking symmetry while they fail to show
: the surprising invariant of the Supergroup. What bagbiters!]

Rubik's note about the size of
the problem says it is 4^4 times bigger than the regular problem.

And it could have been 4^(11/2).
