Integral cayley graphs on powers of Cm

Let G be non-trivial group,S ? G\{1} and S?¹={s?¹|s ? S},also S = S?¹. The Cayley graph of G denoted by ?a(S:G) is a graph with vertex set G and two vertices a and b are adjacent if ab?¹ ? s. A graph is called integral, if its adjacency eigenvalues are integers. In this paper we introduce some infinite families of connected integral Cayley graphs with their spectrum.
