- Abstract
40 years ago, Conway and Sloane proposed using the highly symmetrical Coxeter–Todd lattice <italic>K</italic>12 for quantization, and estimated its second moment. Since then, all published lists identify <italic>K</italic>12 as the best 12-dimensional lattice quantizer. Surprisingly, <italic>K</italic>12 is not optimal: we construct two new 12-dimensional lattices with lower normalized second moments. The new lattices are obtained by gluing together products of two 6-dimensional lattices.
