Abstract:The crossing number of a graph G is the smallest number of pairwise crossings of edges among all the drawings of G in the plane. The pancake graph is an important network topological structure for interconnecting processors in parallel computers. In this paper, we prove the exact crossing number of pancake graph P-4 is six.
