Regular 5-polytopes
Regular 5-polytopes can be represented by the Schläfli symbol {p,q,r,s}, with s {p,q,r} polychoral facets around each face. There are exactly three such regular polytopes, all convex:
- {3,3,3,3} - Hexateron (5-simplex)
- {4,3,3,3} - Penteract (5-hypercube)
- {3,3,3,4} - Pentacross (5-orthoplex)
There are no nonconvex regular polytopes in 5 or more dimensions.

Famous quotes containing the word regular:
“My attitude toward punctuation is that it ought to be as conventional as possible. The game of golf would lose a good deal if croquet mallets and billiard cues were allowed on the putting green. You ought to be able to show that you can do it a good deal better than anyone else with the regular tools before you have a license to bring in your own improvements.”
—Ernest Hemingway (1899–1961)
