One may think of a lattice packing, the particular case where the centers of these spheres are exactly the points of a lattice $L$ or, more generally, of periodic packing when the centers of the spheres are finitely many translates $v_1+L,\dots . I'm going to start by describing a game that seems completely unrelated to sphere packing. Conway andSloane, Sphere Packings, Lattices and Groups, Springer, 1998.

Now one can see that a torus can be made into a group as follows: take the complex plane and set equal to zero all points which are linear integral combinations of two vectors with different directions, say 1 and i. Sphere Packings, Lattices and Groups (Grundlehren der. C is a group and {n + mi, for all n,m, in Z} is a subgroup and you take the quotient group .. It's also involved in a particular construction of the Leech lattice, which is in turn used to construct the famous Monster group. More neat applications of theta functions.
