Determination of matrix-column pairs of symmetry operations 1.2.2.5. Determination of matrix-column pairs of symmetry operations The specification of the symmetry operations by their types, screw or glide components and locations is sufficient to determine the corresponding matrix-column pairs (W, w). The general idea is to determine the ...

Crystallographic symmetry operations
International Tables for Crystallography (2016). Vol. A, Section 1.2.1, pp. 12-13
Crystallographic symmetry operations 1.2.1. Crystallographic symmetry operations Geometric mappings have the property that for each point P of the space, and thus of the object, there is a uniquely determined point , the image point. If also for each image point there is a uniquely determined preimage or original point P, then ...
