Semiregular

A semiregular polytope is a uniform polytope that only contains regular facets. The concept was created as a generalization of uniformity in 3D to higher dimensions, but is now superseded by uniform polytopes. The set of semiregular polytopes is rarely studied.

Convex examples

 * All convex regular polytopes (sometimes excluded)
 * All convex uniform polyhedra (Archimedean solids, prisms, and antiprisms)
 * The k21 family in 4 to 8 dimensions
 * The rectified pentachoron (021) "tetroctahedric"
 * The demipenteract (121) "5-ic semi-regular"
 * The 27-72-peton (221) "6-ic semi-regular"
 * The 126-576-exon (321) "7-ic semi-regular"
