Abstract

A k-containerC(u,v) of a graph G is a set of k-disjoint paths joining u to v. A k-container C(u,v) of G is a k^*-container if it contains all the vertices of G. A graph G is k^*-connected if there exists a k^*-container between any two distinct vertices in G. Let @k(G) be the connectivity of G. A graph G is superconnected if G is i^*-connected for all 1@?i@?@k(G). The pyramid network is one of the important networks applied in parallel and distributed computer systems. The connectivity of a pyramid network is three. In this paper, we prove that the pyramid network PM[n] is 3^*-connected and superconnected for n=1.
