Truncated Tetrahedron, n=12. Polyhedra with extreme distribution of equivalent vertices.

The coordinates of the polyhedron are taken from the applet: Polyhedra whose vertices are equivalent and have an extreme distribution on the same sphere. The first applet sorts and finds the vertices, surface segments, faces, and volume of the polyhedron and its dual image. The second applet colors the edges and faces of the polyhedron and its dual image. All applets are in the Book: Polyhedra with extreme distribution of equivalent vertices : Polyhedra whose vertices are equivalent and have an extreme distribution on the same sphere.
n=12; as Truncated Tetrahedron Vertices: 12 (12) Faces: 8 (4 equilateral triangles + 4 regular hexagons) Edges: 18 The extreme distribution was obtained by me in the applet - "Truncated Tetrahedron. Dependence of the average distance between the vertices of a polyhedron on the truncation parameter. Extreme distribution". Maximization of the average distance between the vertices was performed using truncation parameter.
