**Reiny**, Friday, February 15, 2013 at 9:58amLet's think of the question this way:

Suppose you sit the 6 people around a round table.

Then everybody gives a present to the person on their left.

So everybody has given a present and received a present.

If we change the "arrangement" of the 6 people around the table, we have a different Secret Santa arrangement.

So all we have to do is calculate the number of ways we can sit 6 people around a round table, (or let them form a circle)

that would be 6!/6 = 5! = 120

(I divided by 6. Here is why. If everybody got up and moved one to the right, the order would not change, and we can do that 6 times)
