[QUOTE="StanEvans, post: 5412267, member: 587246"] Sorry I got it wrong, for my example of a 4x4x4 it would be [SUP]64[/SUP][B]C[/B][SUB]32[/SUB]~1.83x10[SUP]18[/SUP]. So with 1 billion it would be 1 billion cubed choose half one billion cubed. I can't find any calculator to find this value, but it will be the 1000000000[SUP]3[/SUP]/2 th entry on the 1000000000[SUP]3[/SUP] th line on Pascal's triangle. [/QUOTE]
