A construction of Small (q-1)-Regular Graphs of Girth 8
Rights accessOpen Access
In this note we construct a new infinite family of (q - 1)-regular graphs of girth 8 and order 2q(q - 1)(2) for all prime powers q >= 16, which are the smallest known so far whenever q - 1 is not a prime power or a prime power plus one itself.
