环带多面体
环带多面体 (全对称多面体)是一种每个面都相对称、相等或与正对的(即将两个面的中心连起可过内接球或外置球球心)面互相对称的立体。
另外,某些卡塔兰立体(半正多面体的对偶多面体)也同样是环带多面体:
其他有菱形面的环带多面体:

Zonohedron 环带多面体![]() A zonohedron is a convex polyhedron where every face is a polygon with point symmetry or, equivalently, symmetry under rotations through 180°. Any zonohedron may equivalently be described as the Minkowski sum of a set of line segments in three-dimensional space, or as the three-dimensional projection of a hypercube. Zonohedra were originally defined and studied by E. S. Fedorov, a Russian crystallographer. More generally, in any dimension, the Minkowski sum of line segments forms a polytope known as a zonotope. |
