## 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
Let IGI be the number of vertices of a graph G and to(G) be the density of G. We call a graph G packed if the clique graph K(G) of G has exactly 2 IGI-O'(G) cliques. We correct the characterization of clique graphs of packed graphs given in Theorem 3.2 of Hedman [3]. All graphs considered here are f
