Abstract

Let \(P_k\) and \(C_k\) respectively denote a path and a cycle on \(k\) vertices. In this paper, we give necessary and sufficient conditions for the existence of a complete \(\left\{P_7,C_6\right\}\)-decomposition of the cartesian product of complete graphs.

Keywords: graph decomposition, path, cycle and product graph
