Let G be a regular graph of girth n( 2 5 ) and valency k ( r 3 ) , that has the least possible number f(k, n ) of vertices. Although the existence of such a graph was proved by Erdos and Sachs (see Ref. 6, p. 82), only a few cases have been solved (see Refs. 2-7). Recently, O'Keefe and Wong have sho

Abstract
With the aid of a computer. we give a regular graph of girth 6 and valency 7, which has 90 vertices and show that this is the unique smallest graph with these properties.

## Abstract The odd girth of a graph __G__ is the length of a shortest odd cycle in __G__. Let __d__(__n, g__) denote the largest __k__ such that there exists a __k__βregular graph of order __n__ and odd girth __g__. It is shown that __d____n, g__ β₯ 2|__n__/__g__β₯ if __n__ β₯ 2__g__. As a consequenc
## Abstract Suppose that __G, H__ are infinite graphs and there is a bijection Ξ¨; V(G) Ξ¨ V(H) such that __G__ β ΞΎ β H β Ξ¨(ΞΎ) for every ΞΎ βΌ __V__(G). Let __J__ be a finite graph and /(Ο) be a cardinal number for each Ο β __V__(J). Suppose also that either /(Ο) is infinite for every Ο β __V__(J) or _
## Abstract We characterize the smallest minimal blocking sets of Q(6,__q__), __q__ even and __q__ β₯ 32. We obtain this result using projection arguments which translate the problem into problems concerning blocking sets of Q(4,__q__). Then using results on the size of the smallest minimal blocking
