text: If in a polyhedron it is possible to orient the faces so that each edge has opposite directions in the two faces which are adjacent along this edge, then the polyhedron is called orientable, otherwise it is called non-orientable (cf. also Orientation).
text: If the faces of a polyhedron can be so oriented that the adja-cent faces assign opposite orientations to their common edge, then the polyhedron is said to be orientable; otherwise the polyhedron is not orientable.
