"WebApr 22, 2024 · The point group of a given space group is the subgroup of symmetry operations that leave one point fixed (i.e. proper and improper rotations). In other words, the point group of a space group is its intersection with O (n). The rotational symmetries of a discrete lattice are limited to 2-, 3-, 4-, and 6-fold.
