| For example, fair dice don't have to be in the shape of regular polyhedra, such as cubes, icosahedra, and so on. |
| The other four were not known to the Greeks, and are sometimes known as the stellated regular polyhedra. |
| This work gave an algebraic classification of maps from polyhedra to spheres. |
| The final part shows how each of the five regular polyhedra can be inscribed in a sphere. |
| The plaque deposits did not form cell casts or polyhedra and did not penetrate into the cell cavities, but were an external deposit only. |
| To solve the problem, Vinson opted to use polyhedra that have more vertices than faces. |
