[4] These naïve definitions are still used. E.g. MathWorld states that the two star polyhedra can be constructed by adding pyramids to the faces of the Platonic solids. [5] [6] This is just a help to visualize the shape of these solids, and not actually a claim that the edge intersections (false vertices) are vertices.
The Kepler–Poinsot polyhedra may be constructed from the Platonic solids by a process called stellation. The reciprocal process to stellation is called facetting (or faceting). Every stellation of one polyhedron is dual , or reciprocal, to some facetting of the dual polyhedron.
It was named by John Horton Conway, extending the naming system by Arthur Cayley for the Kepler-Poinsot solids. The grand 600-cell can be seen as the four-dimensional analogue of the great icosahedron (which in turn is analogous to the pentagram ); both of these are the only regular n -dimensional star polytopes which are derived by performing ...
This was proved by Augustin-Louis Cauchy in 1812 that there are only four regular star polyhedrons, known as the Kepler–Poinsot polyhedron. [2] Brückner's model [3] Brückner (1900) extended the stellation theory beyond regular forms, and identified ten stellations of the icosahedron, including the complete stellation. [4]
Historically, the great dodecahedron is one of two solids discovered by Louis Poinsot in 1810, with some people named it after him, Poinsot solid.As for the background, Poinsot rediscovered two other solids that were already discovered by Johannes Kepler—the small stellated dodecahedron and the great stellated dodecahedron. [3]
There are four regular star polyhedra, known as the Kepler–Poinsot polyhedra. The Schläfli symbol {p,q} implies faces with p sides, and vertex figures with q sides. Two of them have pentagrammic {5/2} faces and two have pentagrammic vertex figures. These images show each form with a single face colored yellow to show the visible portion of ...

The polytopes of rank 2 (2-polytopes) are called polygons.Regular polygons are equilateral and cyclic.A p-gonal regular polygon is represented by Schläfli symbol {p}.. Many sources only consider convex polygons, but star polygons, like the pentagram, when considered, can also be regular.
