HexacodeGraph

The hexacode graph is the incidence graph of the unique symmetric transversal design STD_2[6;3]. It is also a bipartite (0,2)-graph.

The hexacode graph is a distance-transitive graph on 36 vertices having intersection array {6,5,4,1;1,2,5,6}.

It is an integral graph with graph spectrum (-6)^1(-sqrt(6))^(12)0^(10)(sqrt(6))^126^1.

The hexacode graph is implemented in the Wolfram Language as GraphData["HexacodeGraph"].
