Abstract: Research on the cossing number of product graph has been spread to 6-order graph and star graph.In this paper,the authors obtain the crossing numbers of Cartesian products of the 6-vertex graph {P26+e} with the stars Sn is Z(6,n)+4n.
Key words: Cartesian products;crossing number;stars, 6-vertex graph
