Stevinus was the first to show how to model regular and **semiregular** polyhedra by delineating their frames in a plane.

The "rhombic dodecahedron," one of the geometrical **semiregular** solids, is an important crystal form.

- Two Archimedean solids of 26 faces are derived from the coaxial cube, octahedron and **semiregular** (rhombic) dodecahedron (see below).

Other examples of reciprocal holohedra are: the rhombic dodecahedron and cuboctahedron, with regard to the cube and octahedron; and the **semiregular** triacontahedron and icosidodecahedron, with regard to the dodecahedron and icosahedron.

As examples of facial holohedra we may notice the small rhombicuboctahedron and rhombic dodecahedron, and the small rhombicosidodecahedron and the **semiregular** triacontahedron.
