WebA graph is said to be regular of degree r if all local degrees are the same number r. A 0-regular graph is an empty graph, a 1-regular graph consists of disconnected edges, and a two-regular graph consists of one or more (disconnected) cycles. The first interesting case is therefore 3-regular graphs, which are called cubic graphs (Harary 1994, pp. 14-15). … WebHoffman-Singletonov graf je v teoriji grafov 7-regularni neusmerjeni graf s 50 točkami in 175 povezavami.
