Does anyone know of any expository articles on Cayley graphs? I have some background in both group theory and graph theory, and know a little bit of algebraic topology. In particular, I am hoping to find an expository article which explores the graph theory point of view for Cayley graphs, ideally something which starts from the basics, and then goes on to explain some open problems. Does anybody know if anything like this exists?
Thank you in advance.
EDIT: To be more specific, by "graph theory" point of view, I mean something which has as its primary focus the graph theoretic properties of Cayley graphs, such as what is known about hamiltonicity, etc. It would be nice to know what properties of Cayley graphs translate to interesting (deliberately vague) properties of groups.
