Title: Homohedral module

Abstract: The module is a geometric toy block that is designed to imitate the icosahedron's unique ability for three-dimensional intersection with another icosahedron so that a pentangular co-planar line segment that defines the convex pentangular co-planar edge on each icosahedron is shared by both along with a ten faced convex polyhedron.
