Double Circulant Codes over ℤ4 and even Unimodular Lattices

Journal Article (Journal Article)

With the help of some new results about weight enumerators of self-dual codes over ℤ we investigate a class of double circulant codes over ℤ , one of which leads to an extremal even unimodular 40-dimensional lattice. It is conjectured that there should be "Nine more constructions of the Leech lattice". 4 4
