: A (directed) cycle C in a graph is called consistent provided there exists an automorphism of , acting as a 1-step rotation of C. A beautiful but not well-known result of J.H. Co...

Abstract. A k-sized balanced sampling plan excluding contiguous units of order v and index , denoted by BSEC(v, k, ), is said to be bicyclic if it admits an automorphism consisting...

The cone ˆG of a finite graph G is obtained by adding a new vertex p, called the cone point, and joining each vertex of G to p by a simple edge. We show that the rank of the red...
