Locally s‐distance transitive graphs [PDF]

open access: yesJournal of Graph Theory, 2011
AbstractWe give a unified approach to analyzing, for each positive integer s, a class of finite connected graphs that contains all the distance transitive graphs as well as the locally s‐arc transitive graphs of diameter at least s. A graph is in the class if it is connected and if, for each vertex v, the subgroup of automorphisms fixing v acts ...
