On strongly regular self ‐ complementary graphs

Journal of Graph Theory, 1981
AbstractIt is shown that certain conditions assumed on a regular self‐complementary graph are not sufficient for the graph to be strongly regular, answering in the negative a question posed by Kotzig in [1].

Strongly Regular Graphs

2011
A graph (simple, undirected, and loopless) of order v is called strongly regular with parameters v, k,λ,μ whenever it is not complete or edgeless.

Strongly regular vertices and partially strongly regular graphs.

Ars Comb., 2004
Summary: A strongly regular vertex with parameters \((\lambda,\mu)\) in a graph is a vertex \(x\) such that the number of neighbors any other vertex \(y\) has in common with \(x\) is \(\lambda\) if \(y\) is adjacent to \(x\), and is \(\mu\) if \(y\) is not adjacent to \(x\).

On the (99,14,1,2) strongly regular graph

1984
The existence of a strongly regular graph with parameters as in the title is still in doubt. It is proved that there is no such graph with an automorphism of order 11, and the only primes which could divide the order of the automorphism group of such a graph are 2, 3, 5 and 7.
