A new primer on combinatorics that I wrote can be found here. I first cover basic stuff like permutations and combinations. The rest focuses on a more complicated counting problem, which leads to a derivation of the multinomial coefficient. The multinomial coefficient is used in a lot of fields. For instance, it comes up in the derivation of the Boltzmann Distribution in statistical mechanics.
As usual, comments on the document are welcome.

I just came across this post (I was reading back entries) and was really keen to see the primer you wrote--but the link is dead. Could you try posting again? Thanks!
I need to find it, Ben.
