Uniform polyhedra have regular polygon faces and identical vertices. The only convex uniform polyhedra are the five Platonic solids and the 13 Archimedean solids. If we expand the definition to allow interpenetrating faces, we obtain the four Kepler-Poinsot polyhedra and 53 others, for a total of 75.
Solids where faces pass through the center are sometimes called hemihedra. These and some other polyhedra can be considered "one-sided" since both sides of some faces are exposed at various times.
The solids above are derived from the rhombicuboctahedron and rhombicosidodecahedron by faceting, or removing parts of the solid bounded by planes within the solid.
The solids above are derived by faceting the cube and dodecahedron to produce 8/3 and 10/3 faces.
The two solids above have the same vertices and edges as the preceding two pairs, but the 8/3 and 10/3 faces have been faceted to result in intricate rosettes.
The three solids above result from faceting the square faces of a rhombicosidodecahedron
Faceting a dodecahedron results in a family of star-faced polyhedra
The solids above are derived by truncating the great dodecahedron, great icosahedron and great stellated dodecahedron
