ahja, in den FAQ wird's erklärt. sorry:
Strictly speaking there are 52! different deals, about 8x10^67. However,
deals can be transformed in several ways which make no mathematical
difference, which cuts down the number a bit. The four left-hand (7
card) columns can be interchanged in 4! (24) ways, as can the four
right-hand (6 card) columns. Also, suits can be interchanged in certain
ways. If you swap suits so that all the black cards become red and vice
versa (there are 4 ways to do this: SHCD can become HCDS, HSDC, DCHS, or
DSHC respectively), the mathematical properties of the deal do not
change; you can also maintain colors, but swap spades for clubs,
diamonds for hearts, or both (3 more ways). So there are 576
permutations of columns (including no swaps) and 8 permutations of suits
(including no swaps), which reduces the number of essentially different
FreeCell deals to roughly 1.75x10^64 (a few rare deals will be identical
under one of the 4608 transformations). The 32-bit integers used in
FreeCell Pro and other programs can in theory generate 4294967296 deals
(FCPro uses another trick to double this to 8589934592; it appears that
these are all different). The solitaire package Hardwood Solitaire III,
which includes FreeCell among its 100 games, actually allows in theory
for any possible deal to be generated, but at the cost of having to
enter a deal number of up to 68 digits. I do not know if the New Deal
function can actually select every single possible deal.
