An Optimal Odd Unimodular Lattice in Dimension 72

Combinatorics 2012-05-28 v3 Number Theory

Abstract

It is shown that if there is an extremal even unimodular lattice in dimension 72, then there is an optimal odd unimodular lattice in that dimension. Hence, the first example of an optimal odd unimodular lattice in dimension 72 is constructed from the extremal even unimodular lattice which has been recently found by G. Nebe.
