User:Tomruen/Convex regular-faced polyhedra with conditional edges

From Wikipedia, the free encyclopedia

In geometry there are 78 nonconcave polyhedra which made from regular polygon, besides the 91 Johnson solids, the 13 Archimedean solids, and 5 platonic solids, which include 180 degree dihedral angle edges, excluding vertices with 0 degree angle defect. [1]

The bulk of these polyhedra (the 71 containing a rhombus 3+3) were listed by Alex Doskey, Roger Kaufman, and Steve Waterman in 2006. The listing was independently produced and proven complete in 2010 by A. V. Timofeenko.

A conditional edge is an edge which can be removed which doesn't change the geometry of the polyhedron. Pairs of equilateral triangles for example merge into a rhombic face.
