摘要
A connected graph G, all of whose blocks are cycles or cliques, is called a cycle clique graph. Let D be the distance matrix of G. By a theorem of Graham et al., we have det(D) not equal 0 if all cycle blocks have odd vertices. In this paper we give the formula for the inverse of D. (C) 2015 Elsevier Inc. All rights reserved.
