摘要
In this paper, we give a complete description of strongly regular graphs with parameters ((n(2) + 3n - 1)(2), n(2)(n + 3), 1, n(n + 1)). All possible such graphs are: the lattice graph L-3,L-3 with parameters (9, 4, 1, 2), the Brouwer-Haemers graph with parameters (81, 20, 1, 6), and the Games graph with parameters (729, 112, 1,20).
