Abstract
A vertex-transitive graph is said to be 12-transitive if its automorphism group is vertex- and edge- but not arc-transitive. Some recent results on 12-transitive graphs are given, a few open problems proposed, and possible directions in the research of the structure of these graphs discussed.
