A new approach to pancyclicity of Paley graphs I

Abstract

Let $G$ be an undirected graph of order $n$ and let $C_i$ be an $i$-cycle graph. $G$ is called pancyclic if $G$ contains a $C_i$ for any $i\in \{3,4,\ldots,n\}$. We show that the pancyclicity of specific Cayley graphs and the Cartesian product of specific two graphs. As a corollary of these two theorems, we provide a new proof of the pancyclicity of the Paley graph.
