A bicirculant is a graph admitting an automorphism with two cycles of equal length in its cycle decomposition. A graph is said to be arc-transitive if its automorphism group acts transitively on the set of its arcs. This paper gives a complete classification of connected pentavalent arc-transitive bicirculants.

Let X be a connected G-arc-transitive graph, let uv be an arc of X and let L be the permutation group induced by the action of the vertex-stabiliser G_v on the neighbourhood X(v). We study the problem of bounding |G_{uv}| in terms of L and the order of X.
