Nonoverlap of the Star Unfolding
... vertex in an unfolding has total face angle greater than 2π. To create such an overlap, we must start with a vertex in the polyhedron with negative curvature, then cut in such a way that one image of the vertex will retain at least 2π of the surface material. Convex polyhedra clearly avoid 1-local o ...

Apollonian network
In combinatorial mathematics, an Apollonian network is an undirected graph formed by a process of recursively subdividing a triangle into three smaller triangles. Apollonian networks may equivalently be defined as the planar 3-trees, the maximal planar chordal graphs, the uniquely 4-colorable planar graphs, and the graphs of stacked polytopes. They are named after Apollonius of Perga, who studied a related circle-packing construction.
