Let G be a finite group and Cay(G,S) the Cayley graph of G with respect to S. A subset S is called a CI-subset if, for any TCG, Cay(G,S) ~ Cay(G,T) implies S ~ = T for some ct E Aut(G). In this paper, we investigate the finite groups G in which every subset S with size at most m and (S) = G is a CI-

โฆ Synopsis
A restricted edge cut of a graph X is an edge set whose removal disconnects X into nontrivial components. The cardinality of the minimum restricted edge cut is the restricted edge connectivity, denoted by ฮป โฒ (X). If X has restricted edge cuts and ฮป โฒ (X) achieves the upper bound of the restricted edge connectivity, X is said to be ฮป โฒ -optimal. In this work, we will prove that for all but a few exceptions, the mixed Cayley graph is ฮป โฒ -optimal.

A Cayley graph or digraph Cay(G, S) of a finite group G is called a CI-graph of G if, for any T/G, Cay(G, S)$Cay(G, T) if and only if S \_ =T for some \_ # Aut(G). We study the problem of determining which Cayley graphs and digraphs for a given group are CI-graphs. A finite group G is called a conne
It is proven that every connected Cayley graph X , of valency at least three, on a Hamiltonian group is either Hamilton laceable when X is bipartite, or Hamilton connected when X is not bipartite.
