Talk:Tensor product of graphs

From Wikipedia, the free encyclopedia

• The double cover of a complete graph is a complete bipartite graph: K₂ × K_n = K_n,n.

This is not true. For example, take n to be 3. K₂ × K₃ = C₆.

It's the complete graph minus a matching. I took out that line. —David Eppstein 17:11, 12 February 2007 (UTC)
