摘要
We consider strongly regular graphs in which each non-adjacent pair of vertices has exactly one common neighbour. These graphs give rise to partial linear spaces (one of which is a partial quadrangle) and a distance-regular graph of diameter three. The lower bound for the valency of the graph in terms of the number of common neighbours of two adjacent vertices is derived. (C) 2001 Academic Press.
