A graph G is said to be k--critical if the size of any minimum dominating set of vertices is k, but if any edge is added to G the resulting graph can be dominated with k -1 vertices. A graph G is factor-critical if G -v has a perfect matching for every vertex v β V (G) and is bicritical if G -u -v h
## Abstract A graph __G__ is 3βdomination critical if its domination number Ξ³ is 3 and the addition of any edge decreases Ξ³ by 1. Let __G__ be a 3βconnected 3βdomination critical graph of order __n__. In this paper, we show that there is a path of length at least __n__β2 between any two distinct ve
