Semiregular

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 The concept was created as a generalization of uniformity in 3D to higher dimensions, but is now superseded by uniform polytopes.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