Let be a set and
a nonempty family of distinct nonempty subsets of
whose union is
. The intersection graph of
is denoted
and defined by
, with
and
adjacent whenever
and
. Then a graph
is an intersection graph on
if there exists a family
of subsets for which
and
are isomorphic graphs (Harary 1994, p. 19). Graph intersections can be computed in the Wolfram Language using GraphIntersection[g, h].
