Casselman’s Interactive proof (source for next two pictures): ... packing where centers of spheres lie … There are two types of holes in the E 8 lattice: Deep holes such as the point (1,0,0,0,0,0,0,0) are at a distance of 1 from the nearest lattice points. There are 16 lattice points at this distance which form the vertices of an 8-orthoplex centered at the hole (the Delaunay cell of the hole). See more In mathematics, the E8 lattice is a special lattice in R . It can be characterized as the unique positive-definite, even, unimodular lattice of rank 8.

It can be given explicitly by the set of points Γ8 ⊂ R such that • all the coordinates are integers or all the coordinates are half-integers (a mixture of integers and half … See more The automorphism group (or symmetry group) of a lattice in R is defined as the subgroup of the orthogonal group O(n) that preserves the lattice. The symmetry group of the E8 lattice is the Weyl/Coxeter group of type E8. This is the group generated by reflections in … See more The E8 lattice is remarkable in that it gives optimal solutions to the sphere packing problem and the kissing number problem in 8 dimensions. The sphere packing problem asks what is the densest way to pack (solid) n-dimensional … See more
