In geometry, an icositetrahedron is a polyhedron with 24 faces. There are many symmetric forms, and the ones with highest symmetry have chiral icosahedral symmetry: Four Catalan solids, convex: * Triakis octahedron - isosceles triangles * Tetrakis hexahedron - isosceles triangles * Deltoidal icositetrahedron - kites * Pentagonal icositetrahedron - pentagons 27 uniform star-polyhedral duals: (self-intersecting) * Small rhombihexacron, Great rhombihexacron * Small hexacronic icositetrahedron, Great hexacronic icositetrahedron * Great deltoidal icositetrahedron * Great triakis octahedron (Wikipedia).

How to Construct an Icosahedron
How the greeks constructed the icosahedron. Source: Euclids Elements Book 13, Proposition 16. In geometry, a regular icosahedron is a convex polyhedron with 20 faces, 30 edges and 12 vertices. It is one of the five Platonic solids, and the one with the most faces. https://www.etsy.com/lis

Group theory 27: The icosahedral group
This lecture is part of an online math course on group theory. The lecture is about a few examples of groups, in particular the icosahedral group. In it we see that the icosahedral group is the only simple group of order 60, and show that all larger alternating groups are simple.
