Generalized quaternion NCI-groups, NNN-groups and NNND-groups

Jun-Feng Yang, jia-Li Du, Yan-Quan Feng +1

A Cayley (di)graph $\Cay(G,S)$ of a finite group $G$ is called CI if, for every Cayley (di)graph $\Cay(G,T)$ of $G$ , $\Cay(G,S)\cong \Cay(G,T)$ implies that $S^{I ¨} = T$ for some $Ï\i…

The existence of $m$ -Haar graphical representations

Jia-Li Du, Yan-Quan Feng, Binzhou Xia +1

Extending the well-studied concept of graphical regular representations to bipartite graphs, a Haar graphical representation (HGR) of a group $G$ is a bipartite graph whose automor…
