Extremal odd unimodular lattices in dimensions 44, 46 and 47
Masaaki Harada · Hokkaido Mathematical Journal · 2003
In this note, extremal odd unimodular lattices in dimensions 44, 46 and 47 are constructed from self-dual codes over \mathbb{Z}_{4} and \mathbb{Z}_{6} by Construction A. The lattices in dimensions 46 and 47 seem to be the first explicit examples for such lattices.
