We give necessary and sufficient conditions that the complete graph K, has an isomorphic factorization into Kr X K,. We show that this factorization has an application to clone library screening.

Abstract
Let Z~p~ denote the cyclic group of order p where p is a prime number. Let X = X(Z~p~, H) denote the Cayley digraph of Z~p~ with respect to the symbol H. We obtain a necessary and sufficient condition on H so that the complete graph on p vertices can be edgeβpartitioned into three copies of Cayley digraphs of the same group Z~p~ each isomorphic to X. Based on this condition on H, we then enumerate all such Cayley graphs and digraphs. Β© 2006 Wiley Periodicals, Inc. J Graph Theory 52: 243β256, 2006

Let G be a finite group, S a subset of G=f1g; and let Cay Γ°G; SΓ denote the Cayley digraph of G with respect to S: If, for any subset T of G=f1g; CayΓ°G; SΓ ffi CayΓ°G; T Γ implies that S a ΒΌ T for some a 2 AutΓ°GΓ; then S is called a CI-subset. The group G is called a CIM-group if for any minimal gene
For a subset S of a group G such that 1 / β S and S = S -1 , the associated Cayley graph Cay(G, S) is the graph with vertex set G such that {x, y} is an edge if and only if yx -1 β S. Each Ο β Aut(G) induces an isomorphism from Cay(G, S) to the Cayley graph Cay(G, S Ο ). For a positive integer m, th
For a positive integer d, the usual d-dimensional cube Q d is defined to be the graph (K 2 ) d , the Cartesian product of d copies of K 2 . We define the generalized cube Q(K k , d) to be the graph (K k ) d for positive integers d and k. We investigate the decomposition of the complete multipartite
