Small Icosahedron - Tutorial 8
The dodecahedron and the icosahedron are closely related. In mathematics, they are called each others dual.
When you connect the centers of the 12 faces of a dodecahedron, then you get an icosahedron inside that dodecahedron. When you connect the centers of the 20 faces of an icosahedron, then you get a dodecahedron inside that icosahedron.
In nature, it is very rare that crystals appear in the form of an icosahedron. The icosahedron that is sometimes formed by pyrite is known as a Pseudo-icosahedron. Crazy, right? 🤯If this blows your mind, check out pyritohedral symmetry.
