Identification of unimodular lattices of rank 29 without short vectors.
Extension of previous classification results.
Abstract
Pursuing ideas in a recent work of the second author, we determine the isometry classes of unimodular lattices of rank 28, as well as the isometry classes of unimodular lattices of rank 29 without nonzero vectors of norm <=2.
