WebAn arc-transitive graph, sometimes also called a flag-transitive graph, is a graph whose graph automorphism group acts transitively on its graph arcs (Godsil and Royle 2001, p. 59). More generally, a graph G is called s-arc-transitive (or simply "s-transitive") with s>=1 if it has an s-route and if there is always a graph automorphism of G sending each s-route … http://www.faculty.ucr.edu/~hanneman/nettext/C8_Embedding.html
