WebJul 15, 2024 · There are many symmetry point groups, but in crystals they must be consistent with the crystalline periodicity (translational periodicity). Thus, in crystals, only rotations (symmetry axes) of order 2, 3, 4 and 6 are possible, that is, only rotations of 180º (= 360/2), 120º (= 360/3), 90º (= 360/4) and 60º (= 360/6) are allowed.
