文摘Let Г be a simple connected graph and let G be a group of automorphisms of Г. Г is said to be (G, 2)-arc transitive if G is transitive on the 2-arcs of Г. It has been shown that there exists a family of non-quasiprimitive (PSU3(q), 2)-arc transitive graphs where q = 2^3m with m an odd integer. In this paper we investigate the case where q is an odd prime power.
