A graph is called strongly regular with parameters \((v, k, \lambda, \mu)\) if it has \(v\) vertices, each vertex has degree \(k\), two adjacent vertices have precisely \(\lambda\) common neighbors, and two nonadjacent vertices have precisely \(\mu\) common neighbors. We will discuss a few ways of modifying a strongly regular graph such that one obtains more strongly regular graphs with the same parameters.
