Potentially inaccurate statement in examples
I am not an expert on graph theory, so I hesitate to update the article itself. However, I believe the categorical statement:
- The strongly regular graphs with λ=0 are triangle free. The seven listed above are the only known ones.
is incorrect. If I understand the subject correctly, every complete bipartite graph on an even number of vertexes is also strongly regular, with signature srg(2 k, k, 0, k), and bipartite graphs with signature srg(2 k, k, 0, p), with p < k, are easily constructed. — Preceding unsigned comment added by 98.26.29.11 (talk) 12:45, 22 May 2012 (UTC)
