The Augmented Tridiminished Icosahedron
The augmented tridiminished icosahedron is the 64th Johnson solid, or J64 for short. It is bounded by 7 triangles and 3 pentagons, for a total of 10 faces, 18 edges, and 10 vertices. It is constructed by augmenting a tridiminished icosahedron (J63) with a tetrahedron (as a triangular pyramid).
Due to the nonequivalence of its vertices, the augmented tridiminished icosahedron only has a single axis of symmetry: a 3fold symmetry around the line passing through its apex and and the bottom triangle.
