Abstract:

In this talk, we characterise the family of finite arc-transitive bicirculants. We will show that every finite arc-transitive bicirculant is a normal r-cover of an arc-transitive graph that lies in one of eight infinite families or is one of seven sporadic arc-transitive graphs. Moreover, each of these ``basic'' graphs is either an arc-transitive bicirculant or an arc-transitive circulant, and each graph in the latter case has an arc-transitive bicirculant normal r-cover for some integer r.
