The hexacode graph is the incidence graph of the unique symmetric transversal design ![STD_2[6;3]](/images/equations/HexacodeGraph/Inline1.svg)
. It is also a bipartite (0,2)-graph.
The hexacode graph is a distance-transitive graph on 36 vertices having intersection array 
.
It is an integral graph with graph spectrum 
.
The hexacode graph is implemented in the Wolfram
Language as GraphData["HexacodeGraph"].
