Uniform Polytopes in Four Dimensions

|"Polychoron" (plural: polychora) is Olshevsky's term for a four-dimensional polytope, analogous to polygon in two dimensions and polyhedron in three. He includes descriptions and numerical information for all the convex uniform polychora in finite and infinite families: Coxeter-Dynkin graphs, names, symmetry groups, Schlaefli symbol(s), number of elements of each dimension, and vertex figures. Nomenclature; uniform polychora based on the regular pentachoron; the hypercube and regular hexakaidecachoron; the regular icosikaitetrachoron; the regular hecatonkaiicosachoron and regular hexacosichoron; anomalous non-Wythoffian polychoron; prismatic polychora; and uniform polychora derived from hyperspherical tetrahedron B4. Also links to Olshevsky's other two web sites (dinosaurs and custom-built polyhedron models) and to sites with illustrations.|
