The closed neighbourhood of a vertex u of a graph G is u\* = {v 1 v is adjacent to u} U {u}. G is neighbourhood-connected if it is connected, and G -u' is connected but not complete, for al
proved that no minimal imperfect graph has a small transversal, that is, a set of vertices of cardinality at most x + M-1 which meets every c+clique and every x-stable set. In this paper we prove that a slight generalization of this notion of small transversal leads to a conjecture which is as stro
