Abstract

A graph G of order n is called t-edge-balanced if G satisfies the property that there exists a positive λ for which every graph of order n and size t is contained in exactly λ distinct subgraphs of math formula isomorphic to G. We call λ the index of G. In this article, we obtain new infinite families of 2-edge-balanced graphs.
