Crystal Class

You clicked on one of the point group symbols -1, 2/m, or 222. These point groups are the crystal classes for the space groups P-1, P21/c (or C2/c), and P222, respectively. The crystal class is derived from the point group formed by the symmetry operators of the space group with the translational components set to zero.
