Seems we have a winner. At least the 6x6x6 case result gels very nicely with the result from my random approximator: 

C:\test>salva-pc.exe 6 6
the number of patterns is: 000009db3f0a5d231378f10a55ce

C:\test>perl -E"say 0x9db3f0a5d231378f10a55ce / 6**36"
Integer overflow in hexadecimal number at -e line 1.
0.295742865234832

c:\test>851480 -I=1e7 -D=6
  10000000  0.295624800000000

I'll leave the 8x8x6 case running while I sleep.
