Please note: The formula I gave in class for the number of surjective functions from a set X to a set Y is incorrect! Please disregard it. (However, it's a good exercise to try to figure out why it's wrong!) We will find the correct formula later on in this class.

Thanks to Pete Hu for pointing out the error.
