Herlock Sholmes:That would be the case if all 64 pieces were unique, but they're not here.  I haven't got time now to come up with what I think is the right answer, but it will be lower than (8^57)x 7! = 1.5 x 10^55

Herlock Sholmes:
the right formula is 64! / ((8!)^8) = 1,816572393163080675696402792818e+52 which is still more than the amount of cents I have in my bank account.
