A classification of perfect 4-solids
A polytope \(P\) is said to be perfect if it has maximal symmetry properties in the sense that \(P\) cannot be deformed without changing its `shape' or its symmetry group. This notion was introduced and investigated by S. A. Robertson. This paper gives a classification of the perfect 4-solids. The classification in dimension \(n \geq 5\) remains unsolved.
