We prove the following theorem: For a connected noncomplete graph

Then through each edge of G there passes a cycle of length โ‰ฅ min{|V (G)|, ฯ„(G) -1}.

## For a graph G and an integer an independent set of vertices in G}. Enomoto proved the following theorem. Let s โ‰ฅ 1 and let G be a (s + 2)-connected graph.
