Chang graphs

Chang graphs
On the right the three Chang graphs; these graphs are generated by selecting a proper switching set of vertices. On the left the originating triangular graphs T8: the vertices in the switching set are green, the deleted edges are red and new added ones are phantom blue.
Vertices	28
Edges	168
Properties	Strongly regular
v · mathematical field of graph theory, the Chang graphs are a set of three 18-regular undirected graphs, each with 28 vertices and 168 edges. External links Weisstein, Eric W. "Chang Graphs."
