Idealness and 2-resistant sets. (English) Zbl 07165807
Summary: A subset of the unit hypercube $$\{0, 1 \}^n$$ is cube-ideal if its convex hull is described by hypercube and generalized set covering inequalities. In this note, we study sets $$S \subseteq \{0, 1 \}^n$$ such that, for any subset $$X \subseteq \{0, 1 \}^n$$ of cardinality at most 2, $$S \cup X$$ is cube-ideal.
