$Z_{3}^{8}$ is not a CI-group

Joy Morris

A Cayley graph Cay $(G; S)$ has the CI (Cayley Isomorphism) property if for every isomorphic graph Cay $(G; T)$ , there is a group automorphism $α$ of $G$ such that $S^{α} = T$ . The DCI (Di…

Non-Cayley-Isomorphic Cayley graphs from non-Cayley-Isomorphic Cayley digraphs

Dave Witte Morris, Joy Morris

A finite group $G$ is a "non-DCI group" if there exist subsets $S_{1}$ and $S_{2}$ of $G$ , such that the associated Cayley digraphs $C a y (G; S_{1})$ and $C\overrightarrow{…
