Johnson solids

Augmented tridiminished icosahedron

In geometry, the augmented tridiminished icosahedron is one of theJohnson solids (J64). It can be obtained by joining a tetrahedron to another Johnson solid, the tridiminished icosahedron (J63). A Johnson solid is one of 92 strictly convex polyhedra that is composed of regular polygon faces but are not uniform polyhedra (that is, they are not Platonic solids, Archimedean solids, prisms, or antiprisms). They were named by Norman Johnson, who first listed these polyhedra in 1966. (Wikipedia).

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.
