A polyhedral map projection is a map projection based on a spherical polyhedron. Typically, the polyhedron is overlaid on the globe, and each face of the polyhedron is transformed to a polygon or other shape in the plane. The best-known polyhedral map projection is Buckminster Fuller's Dymaxion map. When the … See more The earliest known polyhedral projection is the octant projection developed by Leonardo da Vinci or his associate around 1514, which transforms the faces of an octahedron to Reuleaux triangles.

There are indeed only five regular (convex) polyhedra. And the fact was known to the ancient Greeks. Another term for the regular (convex) polyhedra is Platonic bodies.

So, a face of a map is an n-gon for some n ≥ 3 and two intersecting faces intersect either on a vertex or on an edge. A map on a surface is also called a topological tiling of the surface. If all the faces of a map are triangles then the map is called simplicial. pune rto hypothecation removal online

Convex polyhedra are well-defined, with several equivalent standard definitions. However, the formal mathematical definition of polyhedra that are not required to be convex has been problematic. Many definitions of "polyhedron" have been given within particular contexts, some more rigorous than others, and there is not universal agreement over which of these to choose.
