So, the nonadjacent pairs might have different number of common neighbours, while adjacent pairs have same number of common neighbors. (a cycle graph with n>5 is an example of such a graph). Do you know whether this family of graphs have a particular name in the literature so that I can check for their properties? > > Thank you very much in advance! > > best, > > Gizem Korkmaz > European University Institute > _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
