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
