Equivalence Classes of Full-Dimensional 0/1-Polytopes with Many Vertices

Let $Q_n$ denote the $n$-dimensional hypercube with the vertex set V_n=\{0,1}^n. A 0/1-polytope of $Q_n$ is a convex hull of a subset of $V_n$. This paper is concerned with the enumeration of equivalence classes of full-dimensional 0/1-polytopes under the symmetries of the hypercube. With the aid of a computer program, Aichholzer completed the enumeration of equivalence classes of full-dimensional 0/1-polytopes for $Q_4$, $Q_5$, and those of $Q_6$ up to 12 vertices. In this paper, we present a method to compute the number of equivalence classes of full-dimensional 0/1-polytopes of $Q_n$ with more than $2^{n-3}$ vertices. As an application, we finish the counting of equivalence classes of full-dimensional 0/1-polytopes of $Q_6$ with more than 12 vertices.
