A 27-vertex graph that is vertex-transitive and edge-transitive but not l-transitive
Abstract
Description
I describe a 27-vertex graph that is vertex-transitive and edge-transitive but not 1-transitive. Thus while all vertices and edges of this graph are similar, there are no edge-reversing automorphisms.
