International audienceLet A∈Cn be an extremal copositive matrix with unit diagonal. Then the minimal zeros of A all have supports of cardinality two if and only if the elements of A are all from the set {−1,0,1}. Thus the extremal copositive matrices with minimal zero supports of cardinality two are exactly those matrices which can be obtained by diagonal scaling from the extremal {−1,0,1} unit diagonal matrices characterized by Hoffman and Pereira in 1973
