The Antipode Construction for Sphere Packings

Combinatorics 2015-06-26 v1

Abstract

A construction for sphere packings is introduced that is parallel to the ``anticode'' construction for codes. This provides a simple way to view Vardy's recent 20-dimensional sphere packing, and also produces packings in dimensions 22, 44--47 that are denser than any previously known.
