In this paper, we consider the distance-regular graphs Γ whose distance-2 graphs Γ 2 are strongly regular. Note that if Γ is bipartite, then its distance-2 graph is not connected. We first show that the distance-2 graph of a non-bipartite distance

In this paper we will show that there does not exist a distance-regular graph $\Gamma$ with intersection array $\{80, 54,12; 1, 6, 60\}$. We first show that a local graph $\Delta$ of $\Gamma$ does not contain a coclique with 5 vertices, and then we p

Q-integral graphs are graphs whose signless Laplacians have only integral eigenvalues. The edge-degree of an edge is the number of edges adjacent to the edge. In 2008, S. K. Simic and Z. Stanic studied connected Q-integral graphs with edge-degrees at
