Near-miss Johnson solid

The near-miss Johnson solids meet most of the requirements of being a Johnson solid, but not all of them. Some of them have slightly irregular faces - usually close enough to regular that one can make a physical model with regular faces and not notice a problem. Others may not be strictly convex, meaning they might have coplanar faces or a dihedral angle of 180°.

Polyhedra with coplanar faces can also be considered near-miss Johnson solids.
