Corrigendum: Unimodular Polytopes and Column Number Bounds on Polytopal Totally Unimodular Matrices via Seymour’s Decomposition Theorem

Abstract.

The following is a note that the main results in “Unimodular Polytopes and Column Number Bounds on Polytopal Totally Unimodular Matrices via Seymour’s Decomposition Theorem” [ SIAM J. Discrete Math., 40 (2026), pp. 223–236] follow from Jon Lee’s article “Turán’s Triangle Theorem and Binary Matroids” [ European J. Combin., 10 (1989), pp. 85–90].
