### Congratulations! The numbers

Congratulations! The numbers look incredibly huge although I probably should not be surprised. How long did this take?
Did you use only one computer?

### One computer. The run took a

One computer. The run took a couple of months. In round numbers, the program calculates about 15,000 patterns per second, roughly equivalent to about 720,000 positions per second. It doesn't actually calculate positions. It only calculates patterns. For each pattern, it determines the number of equivalent positions based on the symmetry characteristics of the pattern. I forget the exact model of the computer, but it's a standard Windows desktop, about 3 1/2 years old, so I think the Pentium chip runs at about 2.6Ghz or so.

I use the word "pattern" to denote a respresentative element of a position under symmetery, where for a position x, Rep(x)=min(xm), for all m in M, and where M is the set of 48 rotations and reflections of the cube. So for y=Rep(x), x is the position and y is the pattern. Of course, if y is a pattern, then it is the case that y=Rep(y).

Unfortunately, my program currently does not calculate antisymmetry.
