| 31. | These represent the arrangement of two truncated cubes and one octahedron around the other edges.
|
| 32. | They are generalisations of the three-dimensional cube, tetrahedron and octahedron, respectively.
|
| 33. | The 24-cell consists of 24 octahedrons, joined in 4-dimensional space.
|
| 34. | The cuboctahedron, the truncated cube, and the truncated octahedron each have fourteen faces.
|
| 35. | But the [ Cu ( OH ) 6 ] octahedron is Jahn-Teller distorted.
|
| 36. | This construction has been called a "'triamond stretched octahedron " '.
|
| 37. | Note that this shape is exactly similar to half an octahedron or Johnson solid J 1.
|
| 38. | This octahedron can be divided into 8 tetrahedral volumes, by cutting along the coordinate planes.
|
| 39. | The sharing of an edge or a face of an octahedron gives a structure called bioctahedral.
|
| 40. | It has a regular octahedron core, and shares the same 8 vertices with the cube.
