In geometry, the augmented tridiminished icosahedron is one of the Johnson solids (J64).
A Johnson solid is one of 92 strictly convex polyhedra that have regular faces but are not uniform (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.
It can be obtained by joining a tetrahedron to another Johnson solid, the tridiminished icosahedron.
