Square cupola
In geometry, the square cupola (sometimes called lesser dome) the cupola with octagonal base. In the case of edges are equal in length, it is the Johnson solid, a convex polyhedron with faces are regular. It can be considered as half of the rhombicuboctahedron. It can be used to construct many polyhedrons, particularly in other Johnson solids.
