ABSTRACT: In 1995, Lazebnik and Ustimenko introduced the family of
q-regular graphs D(k, q), which is defined for any positive integer k
and prime power q. The connected components of the graph D(k, q) have
provided the best-known general lower bound on the size of a graph for
any given order and girth to this day.
