algebra to count walks in graphs. Conversely, it is sometimes possible to count the walks by combinatorial reasoning and use the resulting formula to determine the eigenvalues of G. As a first simple example, we consider the complete graph Kp with vertex set V = {v1,...,vp}, and one edge between any two distinct vertices. Thus Kp has pvertices ...So ABC would be one permutation and ACB would be another, for example. In Combinations ABC is the same as ACB because you are combining the same letters (or people). Now, there are 6 (3 factorial) permutations of ABC. Therefore, to calculate the number of combinations of 3 people (or letters) from a set of six, you need to divide 6! by 3!.

Combinatorial proofs are almost magical. Theorem 14.10.2 looks pretty scary, but we proved it without any algebraic manipulations at all. The key to constructing a combinatorial proof is choosing the set S properly, which can be tricky.

Chapter 2 is essentially an algebraic combinatorics, i.e., an application of com-binatorial principle to algebraic systems, including algebraic systems, multi-systems with diagrams. The algebraic structures, such as those of groups, rings, fields and modules were generalized to a combinatorial one. We also consider actions of multi-

Here is a somewhat haphazard list of sources on algebraic combinatorics which appear to be suited to undergraduates (I have not personally read most of them, so I am making semi-educated guesses here).
