| 21. | But that's not to discredit the more measured side of Octahedron.
|
| 22. | Li + Ar 6 is an octahedron shape with Li at the centre.
|
| 23. | The smallest scalenohedron has 8 faces and is topologically identical to the regular octahedron.
|
| 24. | Both tetrahedral positions make the compound stellated octahedron.
|
| 25. | The rectification of a tetrahedron produces an octahedron.
|
| 26. | This makes a " musical geometry " with the geometrical form of the octahedron.
|
| 27. | This also causes the I atom to occupy off centered positions within each octahedron.
|
| 28. | An analogous modification to an octahedron produces an icosahedron, or " snub octahedron ."

| 29. | An analogous modification to an octahedron produces an icosahedron, or " snub octahedron ."
|
| 30. | Its vertex figure is a regular octahedron.
