High Quality Content by WIKIPEDIA articles! In geometry, the truncated octahedron is an Archimedean solid. It has 8 regular hexagonal faces, 6 square faces, 24 vertices and 36 edges. Since each of its faces has point symmetry the truncated octahedron is a zonohedron. A truncated octahedron is constructed from a regular octahedron with side length 3a by the removal of six right square pyramids, one from each point. These pyramids have both base side length, a, and lateral side length, e, of a. The base area is then a². Note that this shape is exactly similar to half an octahedron or Johnson…mehr

High Quality Content by WIKIPEDIA articles! In geometry, the truncated octahedron is an Archimedean solid. It has 8 regular hexagonal faces, 6 square faces, 24 vertices and 36 edges. Since each of its faces has point symmetry the truncated octahedron is a zonohedron. A truncated octahedron is constructed from a regular octahedron with side length 3a by the removal of six right square pyramids, one from each point. These pyramids have both base side length, a, and lateral side length, e, of a. The base area is then a². Note that this shape is exactly similar to half an octahedron or Johnson solid J1. All permutations of (0, ±1, ±2) are Cartesian coordinates of the vertices of a truncated octahedron centered at the origin. The vertices are thus also the corners of 12 rectangles whose long edges are parallel to the coordinate axes. The truncated octahedron can also be represented by even more symmetric coordinates in four dimensions: all permutations of (1,2,3,4) form the vertices of a truncated octahedron in the three-dimensional subspace x + y + z + w = 10. Therefore, the truncated octahedron is the permutohedron of order 4.
