Abstract

The exact values of crossing numbers of the Cartesian products of four special graphs of order five with cycles are given and, in addition, all known crossing numbers of Cartesian products of cycles with connected graphs on five vertices are summarized.

Keywords: graph, drawing, crossing number, cycle, Cartesian product.

2000 Mathematics Subject Classification: 05C10, 05C38.
