4Circle packing theorem — Example of the circle packing theorem on K5, the complete graph on five vertices, minus one edge. The circle packing theorem (also known as the Koebe–Andreev–Thurston theorem) describes the possible tangency relations between circles in the plane …
5Close-packing of spheres — hcp and fcc close packing of spheres In geometry, close packing of spheres is a dense arrangement of equal spheres in an infinite, regular arrangement (or lattice). Carl Friedrich Gauss proved that the highest average density – that is, the… …
6Circle packing — This article describes the packing of circles on surfaces. For the related article on circle packing with a prescribed intersection graph, please see the circle packing theorem. The most efficient way to pack different sized circles together is… …
7Apollonian sphere packing — is the three dimensional equivalent of the Apollonian gasket. The principle of construction is very similar: if you have any four spheres which are cotangent to each other, it is then possible to construct two more spheres which are cotangent to… …
