   Linked via "rotation elements"

   Point Groups
   Point groups describe the symmetries of an object that leave at least one point fixed. In crystallography, there are 32 crystallographic point groups, determined by combinations of rotation axes and reflection planes that are compatible with the underlying lattice structure. The classification relies heavily on the order of the rotation elements.
