A graph G of order n > 2 is pancyclic if G contains a cycle of length l for each integer l with 3 ≤ l ≤ n and it is called vertex-pancyclic if every vertex is contained in a cycle of length l for every 3 ≤ l ≤ n. A graph G of order n > 2 is Hamilton-connected if for any pair of distinct vertices u and v, there is a Hamilton u-v path, namely, there is a u-v path of length n − 1. The graph B(n) is a graph with the vertex setIn this paper, we show that the graph L(n) is vertex-pancyclic and Hamilton-connected whenever n ≥ 6.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
