Uniform polyhedron   (anglický)

Definícia vek 16 úroveň 3

A uniform polyhedron is a polyhedron which has the same pattern of faces around each vertex. Assuming that only two faces are allowed to meet at an edge, there are 75 such polyhedra. All but one of them can be specified by a Wythoff symbol.
The vertices of such a polyhedron lie on a sphere. The centre of the sphere is the centroid of the polyhedron. For a given vertex, the set of vertices joined to it by an edge lie on a circle.
