Let k greater than or equal to 2 be an integer. A k-factor F of a grap
h G is called a hamiltonian k-factor if F contains a hamiltonian cycle
. In this paper, we shall prove that if G is a graph of order n with k
greater than or equal to 2, n greater than or equal to 8k - 4, kn eve
n and delta(G) greater than or equal to n/2, then G has a hamiltonian
k-factor. (C) 1997 John Wiley & Sons, Inc.
