Refined Configuration Results for Extremal Type II Lattices of Ranks 40 and 80
(American Mathematical Society, 2010)We show that, if \(L\) is an extremal Type II lattice of rank 40 or 80, then \(L\) is generated by its vectors of norm \(min(L)+2\). This sharpens earlier results of Ozeki, and the second author and Abel, which showed that ...
