... square-counting or an interlacing argument, one can show that the max-
imum number of vertices in an independent set in the Hoffman-Singleton graph is 15. If
S is an independent set of size 15 in this ... Then H is the Hoffman-Singleton graph.
Note that we may view the vertices in S as points and the vertices not in S as lines,
with a point and line incident if the corresponding verti...
