The Kepler-Poinsot solids, named after Johannes Kepler and Louis Poinsot

               (17th -19th century), are four regular concave polyhedra with intersecting facial
               planes. These can be obtained by stellating Platonic solids. Only two of the four
               are shown below. The two not shown are the Great Dodecahedron and the Great
               Icosahedron.
