Counterexample to a conjecture of Ziegler concerning a simple polytope and its dual

Combinatorics 2020-04-27 v1

Abstract

Problem 4.19 in Ziegler's "Lectures on Polytopes" asserts that every simple 33-dimensional polytope has the property that its dual can be constructed as the convex hull of a subset of the vertices of the original simple polytope. In this note we state a higher-dimensional analogue of this conjecture and provide a family of counterexamples for dimension d3d \geq 3.
