Simplex faces of order and chain polytopes

Combinatorics 2025-09-11 v4

Abstract

It will be proved that a kk-clique in the 11-skeleton of either the order polytope or the chain polytope corresponds to the (k1)(k-1)-face, which is a simplex, in each polytope. These results generalize the known explicit descriptions of edges and triangular 22-faces of each polytope.
