摘要

Let G be a group and let S be an inverse-closed and identity free generating set of G. The Cayley graph Cay(G, S) has vertex-set G and two vertices u and v are adjacent if and only if uv(-1) is an element of S. Let CAY(d)(n) be the number of isomorphism classes of d-valent Cayley graphs of order at most n. We show that log(CAY(d)(n)) is an element of circle minus(d(log n)(2)), as n -> infinity. We also obtain some stronger results in the case d = 3.
