For other uses, see Facetting (disambiguation).
For example the small stellated dodecahedron and great icosahedron are two facetings of the icosahedron:
|icosahedron||small stellated dodecahedron||great icosahedron|
Faceting has not been studied as extensively as stellation.
- In 1619, Kepler described a regular compound of two tetrahedra which fits inside a cube, and which he called the Stella octangula. This seems to be the first known example of faceting.
- In 1858, Bertrand derived the regular star polyhedra (Kepler–Poinsot polyhedra) by faceting the regular convex icosahedron and dodecahedron.
- In 1974, Bridge enumerated the more straightforward facetings of the regular polyhedra, including those of the dodecahedron.
- In 2006, Inchbald described the basic theory of faceting diagrams for polyhedra. For a given vertex, the diagram shows all the possible edges and facets (new faces) which may be used to form facetings of the original hull. It is dual to the dual polyhedron's stellation diagram, which shows all the possible edges and vertices for some face plane of the original core.
