Abstract: A graph on $2n$  is a bicirculant if it admits an automorphism that  is a permutation with two cycles of length $n$. For example, the Petersen and Heawood graphs. Arc-transitive bicirculants of valencies three, four and five have previously been classified by various authors. In this talk I will discuss recent joint work with Alice Devillers and Wei Jin that characterises all arc-transitive bicirculants and provides a framework for their complete classification.
