NEW METHOD RELATES PENTAGON TILE PATTERNS TO OPEN PACKINGS OF ICOSAHEDRA

Abstract: It is not possible to tile the plane with regular pentagons without gaps. If the gap areas are defined as black voids, then a binary coloring scheme can be used to differentiate the pentagon tiles into two groups. I have devised a new method using this scheme to describe any pentagon tiling of regular pentagons as a cross section of an open packing of icosahedra. I will demonstrate how to use this method to construct an open packing of icosahedra from a pentagon-rhombus tiling. After that, I will demonstrate how to expand it into an aggregate of dodecahedra interspaced with pentagonal antiprisms.
