Soicher Graphs

Download Wolfram Notebook

The Soicher graphs are three distance-regular graphs on 5346, 486, and 315 vertices, respectively. The first two are also distance-transitive but the third is not.

The second and third Soicher graphs are implemented in the Wolfram Language as GraphData["Soicher", n] for .
