The great stellated dodecahedron is one of the four Kepler-Poinsot Star Polyhedra, and is also the third and final stellation of the dodecahedron. |
The small stellated dodecahedron is simply 12 stars, called pentagrams, intersected in a special way. |
The great stellated dodecahedron, first described by 17th-century mathematician Johannes Kepler, is one example of a spiky polyhedron. |
More precisely stellated polyhedron faces are formed by interpenetrated stellated polygons. |
The other four were not known to the Greeks, and are sometimes known as the stellated regular polyhedra. |
They are monopetalous, small, white, stellated in six points. |
