Title: Fun with Exponential Generating Functions

Abstract:

Exponential generating functions provide a clever way to count sets, where order is not important - as opposed to ordinary generating functions, which usually count structured objects where order counts.
We'll see some uses of their power - even a combinatorial proof of the Pythagorean Theorem.
