A class of graphs is a benefit of graphs closed under isomorphism. We have seen previously a variety of classes of graphs: whole graph, cycle graphs, linked graphs. Many more classes can be distinct by means of a variety of graph parameters. S(Ln) is a pair sum graph, where Ln is a ladder on n vertices.
