Wikipedia:WikiProject Uniform Polytopes



Welcome to WikiProject Uniform Polytopes, the WikiProject which aims to improve Wikipedia's coverage of uniform polytopes! A uniform polytope is an extension to the regular polytopes, including regular and semiregular polytopes, being vertex transitive, and having regular polygon faces.

Regular polytopes are identified by Schläfli symbols. Uniform polytopes are (nearly all) identified by Coxeter–Dynkin diagrams, existing in Coxeter group symmetry families. These are called Wythoffian, being generated by reflection symmetry called a Wythoff construction. Most of the remaining nonwythoffian forms are generated by operational modifications on the reflective forms.

 * All links to Richard Klitzing's site have to be updated as the address moved from ogre.nu to bendwavy.org in January 2011.

Tasks

 * Create a template navigator:
 * Template:Polytopes - started with list of polytopes by dimension

Members

 * 1) Tom Ruen (talk) - I referenced all the wiki articles I know related to this topic, still quite unsure what the immediate goals for this project should be.
 * 2) Mateus Zica - i'm here to help!
 * 3) Double sharp - I will usually stick to the polychora, polytera, and polypeta but may sometimes venture out into higher dimensions.
 * 4) OfficialURL  (talk) – As with WikiProject Polyhedra, I'll translate articles to Spanish.
