Normality Of Four Degree Cayley Graphs For One Classe Of Order6p~2Groups

Let G be a finite group and T a subset of G such that1(?)T. A Cayley graph X=Cay(G, T) of group G is said to be normal if R(G), the group of right multiplications is normal in Aut(X). In this paper, by investigating the normality, we classify4-valent Cayley graphs of one group of order6p2, G=<a, b|a3p2=b2=1,ab=a2p2-1>,in this paper,we obtain an infinite families of nonnormal Cayley graphs.
