The Delsarte graph is a strongly regular graph on 243 vertices with regular parameters (nu,k,lambda,mu)=(243,110,37,60).

It is distance-regular as well as distance-transitive with intersection array {110,72;1,60} and has graph spectrum (-25)^(22)2^(220)110^1.

It is implemented in the Wolfram Language as GraphData["DelsarteGraph"].
