 Blackman's theorem

Blackman's theorem is a result in the field of combinatorial geometry and number theory, specifically concerning the distribution of points in the plane or higher-dimensional spaces. The theorem is often discussed in the context of packing or covering problems, where one examines how to optimally arrange points or shapes in Euclidean space. One of the key implications of Blackman's theorem is related to the covering and packing densities of spheres in different dimensions.
