\(E_6\) lattice-shell code
Description
Spherical code whose codewords are points on the \(E_6\) lattice normalized to lie on the unit sphere.
The minimal shell of the lattice yields the \((6,72,1)\) code, whose codewords form the vertices of the \(1_{22}\) real polytope and the rectified Hessian polyhedron.
