List of near-miss uniform polytopes

From Polytope Wiki
Jump to navigation Jump to search

A near-miss uniform polytope is an isogonal polytope which has almost uniform facets (slightly irregular polygons for near-miss uniform polyhedra).

Edges of near-miss uniform polytopes have different lengths but the ratio between the longest and the shortest edge lengths should be 1 ≤ Δ ≤ 1.1.

Some of them can also be semi-uniform.
