On two classes of polyhedra with rhombic vertices

Two classes of closed convex polyhedra in $E^3$ ($RS$- and $RR$-polyhedra) are introduced; the stars of some vertices of the polyhedra under consideration consist of equal rhombi. In addition to the complete enumeration of $RS$-polytopes, the proof of the existence of two polyhedra of the class $RR$ is given.
