Convex hulls of finite packs of spheres

The first picture shows a minimal sphere packing that is more efficient than the linear 3-dimensional sphere packing. Download from here the project report on convex hulls of finite packs of spheres to read why this is of interest, and for a description of a record-breaking 4-dimensional analogue. The following five pictures are sphere packings obtained from the five platonic solids.







Punctured torus group actions

Convex hulls of hyperbolic limits sets, various parameters, and an anti-de Sitter limit set.
