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.
