Kreweras conjectured that every perfect matching of a hypercube Q n for n≥ 2 can be extended to a hamiltonian cycle of Q n. Fink confirmed the conjecture to be true. It is more general to ask whether every perfect matching of Q n for n≥ 2 can be extended to two or more hamiltonian cycles of Q n. In this paper, we prove that every perfect matching of Q n for n≥ 4 can be extended to at least 2 2 n− 4 different hamiltonian cycles of Q n.
