Source sentences:
text: It is caused by either a mirror plane reflecting the face from one side of the crystal to the other, a two fold rotational axes rotating the face from one side to the other or simply a center of symmetry (see the triclinic symmetry class) where an inversion of the face takes place through the center of the crystal.
