As we have seen, this is a stronger property than being either vertex transitive or edge transitive, and so we can say even more about arc-transitive graphs. The first few sections of this chapter consider the basic theory leading up to Tutte’s remarkable results on cubic arc-transitive graphs

We consider the relationship between homomorphisms and graph products, and in particular a famous unsolved conjecture of Hedetniemi, which asserts that if two graphs are not .-colour

A connected strongly regular graph with connected complement is just a distance-regular graph of diameter two. Any vertex-transitive graph with a ra
