| More precisely stellated polyhedron faces are formed by interpenetrated stellated polygons. |
| In the low-calcium orthorhombic pyroxenes, M2 contains magnesium and iron, and the polyhedron takes on a more regular octahedral shape. |
| The fifth regular polyhedron, the dodecahedron, was left over, so Plato proposed rather lamely that the god used it up for decorating the universe. |
| The faces of the polyhedron appear to consist of two equilateral triangles and six somewhat irregular pentagons. |
| In the first place, each of these figures may be conceived as an orthogonal projection of a closed plane-faced polyhedron. |
| Designed as a casing for a technical duct, this mosaic in glass paste is produced on a polyhedron. |
