## Abstract The __clique graph__ of a graph is the intersection graph of its (maximal) cliques. A graph is __self‐clique__ when it is isomorphic with its clique graph, and is __clique‐Helly__ when its cliques satisfy the Helly property. We prove that a graph is clique‐Helly and self‐clique if and o
This paper examines the class ofbipartite permutation graphs. Two chaiacterizations of graphs i n this class are presented. These characterizations l ead to a linear time recognition algorithm, and to polynomial time algorithms for a number of NP-complete problems when restricted to graphs i n this
