ऑक्टाहेड्रन इसके अंग्रेजी अर्थ का उदाहरण

This construction can be called a retrosnub tetrahedron or retrosnub tetratetrahedron, similar to the snub tetrahedron symmetry of the icosahedron, as a partial faceting of the truncated octahedron (or omnitruncated tetrahedron): .

It can also be constructed with 2 colors of triangles and pyritohedral symmetry as, or , and is called a retrosnub octahedron.

For N"nbsp;"nbsp;6, electrons reside at vertices of a regular octahedron.

The join of a square with a third pair of isolated points is an octahedron (again, without interior).

Each edge of the cuboctahedron represents a peripheral Au–Au bond.

The cuboctahedron has 24 edges while the icosahedron has 30 edges; the transition from cuboctahedron to icosahedron is favored since the increase in bonds contributes to the overall stability of the icosahedron structure.

An octahedron may then form with a radius ratio greater than or equal to .

The other two, less stable, forms are brookite and anatase, in which each octahedron shares three and four edges respectively with adjoining octahedra.

If all edges of a square pyramid (or any convex polyhedron) are tangent to a sphere so that the average position of the tangential points are at the center of the sphere, then the pyramid is said to be canonical, and it forms half of a regular octahedron.

The +Teamgeist ball differs from previous balls in having just 14 curved panels (making the ball topologically equivalent to a truncated octahedron), rather than the 32 that have been standard since 1970.

A regular octahedron augmented by 2 regular tetrahedra creates a trigonal trapezohedron, with coplanar equilateral triangles merged into 60-degree rhombic faces.

In this context the tetragonal trapezohedron has also been called the cubical octahedron, quadrilateral octahedron, or octagonal spindle, because it has eight quadrilateral faces and is uniquely defined as a combinatorial polyhedron by that property.

Adding four cuboids to a mesh for the cubical octahedron would also give a mesh for Schneiders' pyramid.
