WebMar 28, 2024 · In Chapter 5 we have seen several extremal problems concerning families of points on the sphere whose solutions, with a n appropriate number of points, formed the configuration of vertices of a regular polyhedron with triangular faces. Now an interesting problem arises for the best distribution of, say, 7 points. In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or hypersphere packing in higher dimensions) or to non-Euclidean spaces such as hy…
