![]() | Pentagonal Rotunda (J6) |

One of the 92 Johnson solids, which are non-uniform convex regular-faced polyhedra. This one has 5-fold pyramidal symmetry, and may be thought of as one half of an icosidodecahedron.
J6 has been useful in constructing Stewart toroids, such as the drilled pentagonal rotunda, the rotunda-drilled truncated icosidodecahedron, and this more recently discovered genus-41 Stewart toroid.
