High Quality Content by WIKIPEDIA articles! In geometry, the tridiminished icosahedron is one of the Johnson solids (J63). The 92 Johnson solids were named and described by Norman Johnson in 1966. In geometry, a Johnson solid is a strictly convex polyhedron, each face of which is a regular polygon, but which is not uniform, i.e., not a Platonic solid, Archimedean solid, prism or antiprism. There is no requirement that each face must be the same polygon, or that the same polygons join around each vertex. An example of a Johnson solid is the square-based pyramid with equilateral sides (J1); it has 1 square face and 4 triangular faces.
