Let G be a k-regular graph, with girth 5 and diameter 2.Then, k is in {2,3,7,57}. For k=2, the graph is C 5.For k=3, the graph is the Petersen graph.For k=7, the graph is called the Hoffman-Singleton graph.Finding a graph for k=57 is still open, as far as I know. Hoffman and Singleton proved more: There is an obvious lower bound on f(m,n), …
