Graduate combinatorics

[waht]

What's a good graduate level introductory combinatorics text. I've been looking at Cameron and Van Lint-Wilson, they seem like sound texts. Do you guys have any recommendations?

You also need to study mathematical physics techniques used to solve 2 dimensional lattice models, like the Yang-Baxter equation, Fermionic methods using the Pfaffian, etc. You can dowload the book: "Exactly Solved Models in Statistical Mechanics" by Baxter free of charge from this site:

Note that Baxter doesn't call his own equation the "Yang-Baxter" equation in his own book.
