Conventional Crystallographic Point Groups
A three-dimensional point group is a group of symmetry operators which acts at a fixed point O, and leaves invariant all distances and angles in a three-dimensional Euclidean space. The symmetry operators having these properties are rotations about the axes through O, or products of such rotations and the inversion. Such products, of course, include reflections in planes through O.
