Coxeter-Todd \(K_{12}\) lattice[1]
Description
Even integral lattice in dimension \(12\) that exhibits optimal packing. It's automorphism group was discovered by Mitchell [2]. For more details, see [4][3; Sec. 4.9].
Protection
The \(K_{12}\) lattice exhibits the densest known lattice packing in 12 dimensions.'
