Ra or Sa (the subscript a refers to the axial chirality), to chiral configurations of this kind the structure must be viewed from one end of the stereogenic axis (it doesn't matter which). Since no chiral center exists in this molecule, its chirality is due to the dissymmetric orientation of substituents about a chiral axis (the axis defined by the three carbon atoms of the double bonds). The S 4 rotation-reflections and the mirror planes have been removed. Assign the following molecules to point groups: tetrafluorocubane, C8H4F4.
