A consecutive-d digraph with n nodes is a digraph whose nodes are labeled by the residues modulo n and a link from node i to node j exists iff j=qi+r,qi+r+1,...,qi+r+d-1 (mod n) where q and r are given. Many computer networks and multiprocessor systems use consecutive-d digraphs as their interconnection networks. A digraph is called Hamiltonian if it contains a spanning circuit. The Hamiltonian property provides the capability of configuring the interconnection network as a linear array, which is the configuration with broadcast practical significance of either n - 1 or n nodes in the presence of a single faulty node or link. Characterization of Hamiltonian consecutive-1 digraph has been previously given. In this paper, we prove that for gcd(n, q) 1 the consecutive-d digraph is Hamiltonian iff d = gcd(n, q); and for gcd(n, q) = 1 it is Hamiltonian if d = 5.
