A limit theorem for the Shannon capacities of odd cycles. II

It follows from a construction for independent sets in the powers of odd cycles given in the predecessor of this paper that the limit as goes to infinity of is zero, where is the Shannon capacity of a graph . This paper contains a shorter proof of this limit theorem that is based on an `expansion process' introduced in an older paper of L. Baumert, R. McEliece, E. Rodemich, H. Rumsey, R. Stanley and H. Taylor. We also refute a conjecture from that paper, using ideas from the predecessor of this paper.
