regular Polygon and StarPolygon A geometric closed figure with more than 3 sides is called a polygon. If all vertices are coplanar we have a plane polygon. A plane polygon is "regular", if it is equilateral and equiangular. Regular polygones are labeled with {p}. The "p" counts the sides/angles. For instance a square has the label {4}. A "Star Polygon" is labeled with {p/q}(means every qth point is connected). JAR with Sources 

superposing all the Stars for a given p exist a set of Starpolygons... JAR with Sources 

uniform Polyhedra  Z Sorting
Algorithm (right Click turns a face off) A polyhedron consist of a finite set of plane polygons("faces"), joined at their sides("edges"). Regular polyhedra have regular faces and regular vertex figures. A vertex figure is a polygon formed by connecting the midpoints of all adjacent sides of a vertex. The {p, q} is the label("Schläfli Symbol") for that solids. The p describes the polygons, and the q the count of that polygons at each vertex. JAR with Sources
