Emília Draženská, Marián Klešč · Discussiones Mathematicae Graph Theory · 2011
The crossing numbers of Cartesian products of paths, cycles or stars with all graphs of order at most four are known.The crossing numbers of G2C n for some graphs G on five and six vertices and the cycle C n are also given.In this paper, we extend these results by determining crossing numbers of Cartesian products G2C n for some connected graphs G of order six with six and seven edges.In addition, we collect known results concerning crossing numbers of G2C n for graphs G on six vertices.
