Rank 72 high minimum norm lattices

Robert L. Griess

Given a polarization of an even unimodular lattice and integer $k \geq 1$ , we define a family of unimodular lattices $L (M, N, k)$ . Of special interest are certain $L (M, N, 3)$ of rank 72…

Midwest cousins of Barnes-Wall lattices

Robert L. Griess

Given a rational lattice and suitable set of linear transformations, we construct a cousin lattice. Sufficient conditions are given for integrality, evenness and unimodularity. Whe…
