Problem: Given the question: Information:  - The Multinational Aircrew Electronic Warfare Tactics Facility Polygone - POLYGON is an Electronic Warfare Tactics Range located on the border between Germany and France. It is a tri-national facility operated by France, Germany and the United States.  - In elementary geometry, a polyhedron (plural polyhedra or polyhedrons) is a solid in three dimensions with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek , as "poly-" (stem of , "many") + "-hedron" (form of , "base" or "seat").  - In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.  - A hexahedron ( plural : hexahedra ) is any polyhedron with six faces . A cube , for example , is a regular hexahedron with all its faces square , and three squares around each vertex . There are seven topologically distinct convex hexahedra , one of which exists in two mirror image forms . ( Two polyhedra are `` topologically distinct '' if they have intrinsically different arrangements of faces and vertices , such that it is impossible to distort one into the other simply by changing the lengths of edges or the angles between edges or faces . ) There are three further topologically distinct hexahedra that can only be realised as concave figures :    Given the information, choose the subject and object entities that have the relation of 'has facet polytope'.
