New ‐Edge‐Balanced Graphs from Bipartite Graphs

Let G be a graph of order n satisfying that there exists for which every graph of order n and size t is contained in exactly λ distinct subgraphs of the complete graph isomorphic to G. Then G is called t‐edge‐balanced and λ the index of G. In this article, new examples of 2‐edge‐balanced graphs are constructed from bipartite graphs and some further methods are introduced to obtain more from old.
