In geometry, the triaugmented hexagonal prism is one of the Johnson solids (J57).
A Johnson solid is one of 92 strictly convex regular-faced polyhedra, but which is not uniform, i.e., not a Platonic solid,Archimedean solid, prism or antiprism. They are named by Norman Johnson who first enumerated the set in 1966.
