Sphere packing

Comments

Sphere packing has various applications in error-correcting codes (cf. Error-correcting code), the channel coding problem, Steiner systems (cf. Steiner system), -designs, and in the theory of finite groups. The most important special case is the sphere packing in via the Leech lattice. Finite and infinite sphere packing in has applications in classical and modern crystallography (cf. Crystallography, mathematical). J.H. Conway, N.J.A.
