EdgeTransitiveGraphQ

EdgeTransitiveGraphQ[g]

yields True if the graph g is a edgetransitive graph and False otherwise.

Details

  • A graph g is edge transitive if for any edges e1 and e2 of g, there is an automorphism of g that maps e1 to e2.
  • EdgeTransitiveGraphQ is typically used to test whether all edges in a graph have identical neighborhoods.
