Abstract :
We prove that a k-ary 2-cube Q2k with three faulty edges but where every vertex is incident with at least two healthy edges is bipancyclic, if k ≥ 3, and k-pancyclic, if k ≥ 5 is odd (these results are optimal). We go on to show that when k ≥ 4 is even and n ≥ 3, any k-ary n-cube Qnk with at most 4n-5 faulty edges so that every vertex is incident with at least two healthy edges is bipancyclic, and that this result is optimal.
