Part of the reflections overlaps exactly, while others are non-overlapped. A typical example is an obverse/reverse twin in case of a rhombohedral crystal.
Some of the reflections overlaps exactly, while others are non-overlapped. A typical example is an obverse/reverse twin in case of a rhombohedral crystal. Thus, this kind of twinning lets R3 look like P3<sub>1,2</sub>, and R32 like P3<sub>1,2</sub>21. However, 1/3 of all reflections are still zero.
