E8 Lattice: Optimal Packing in Dimension 8

E8Lattice Dimension8 LatticeTheory ExceptionalStructures

In 2016, Maryna Viazovska proved the E8 lattice provides optimal sphere packing in eight dimensions—a breakthrough solving a problem where most dimensions remain unsolved.

Sphere Packing: Kepler to Higher Dimensions
