Erratum: Critical Cutsets of Graphs and Canonical Facets of Set Packing Polytopes (Mathematics of Operations Research, Vol. 2, 1977, 15–19)

Theorem 2, published in the paper “Critical cutsets of graphs and canonical facets of set packing polytopes,” (Mathematics of Operations Research, Vol. 2, No. 1, pp. 15–19, 1977) as stated is false, the conditions given are not sufficient to define a facet of P(G). We are grateful to Sven de Vries for querying us about a flaw in our proof. A correction of condition (ii) of Theorem 2 is given.
