• Cayley graph
• regular p-group

In [2] it is proved that if X = Cay(G, S) is a connected tetravalent Cayley graph on a regular p-group G (for p not equal 2, 5), then the right regular representation of G is normal in the automorphism group of X. In this paper we prove that a similar result holds, for p = 5, under a slightly stronger hypothesis. Some remarkable examples are presented.
