A node of a graph G, thought of as representing a communication network, is said to be redundant provided that its removal does not diminish the connectivity. In constructing networks, we require reliable connectedness in addition to the usual requirement of reliability (i.e., the higher the connect

Abstract
A graph L is called a link graph if there is a graph G such that for each vertex of G its neighbors induce a subgraph isomorphic to L. Such a G is said to have constant link .L Sabidussi proved that for any finite group F and any n β©Ύ 3 there are infinitely many nβregular connected graphs G with Aut__G β Ξ. We will prove a stronger result: For any finite group Ξ and any link graph L with at least one isolated vertex and at least three vertices there are infinitely many connected graphs G with constant link L and Aut__G β Ξ.

Given a graph G, its odd set is a set of all integers k such that G has odd number of vertices of degree k. We show that if two graphs G and H of the same order have the same odd sets then they can be obtained from each other by succesive application of the following two operations: β’ add or remove
## Abstract The girth pair of a graph gives the length of a shortest odd and a shortest even cycle. The existence of regular graphs with given degree and girth pair is proved and simple bounds for their smallest order are developed. Several infinite classes of such graphs are constructed and it is
## Abstract For a positive integer __n__ and a finite group __G__, let the symbols __e__(__G, n__) and __E__(__G, n__) denote, respectively, the smallest and the greatest number of lines among all __n__βpoint graphs with automorphism group __G__. We say that the Intermediate Value Theorem (IVT) hol
This paper considers the (A, 0 ) problem: to maximize the order of graphs with given maximum degree A and diameter 0, of importance for its implications in the design of interconnection networks. Two cubic graphs of diameters 5 and 8 and orders 70 and 286, respectively, and a graph of degree 5, diam
