Re: How many ways can you arrange a deck of cards?

Ok someone has already thought about it... http://en.wikipedia.org/wiki/Out_shuffle
For a deck with n cards (n even) we need k shuffles, where k is the least number so that n-1 that divides 2^k-1.

Re: How many ways can you arrange a deck of cards?

As a side note, a 52-card deck needs 8 perfect faro shuffles in order to restore the deck to its original state. You would think that the more cards you have the worse it gets...wrong. For example you need 10 perfect shuffles for a 12-card deck, 100 shuffles for a 102-card deck, 10 shuffles for a 10...

Correct...2^52 times 52!. For each of the 52! permutations there are 2^52 ways to switch each card up or down.
