Figure 4
Symmetry operations (or general positions) of the subgroup with space-group type Cm and listed as 3.1 in the first row of Fig. 3, as obtained when clicking in the column `Symmetry operations' (`Matrix form'). Only one operation is listed, as a representative, for each set of operations differing by lattice translations of the subgroup. In this simple case the list is reduced to two operations. They are described in different formats, including the Seitz notation, and are given both in the basis generating the lattice of the subgroup (left-hand columns) and in the parent unit-cell basis (right-hand columns). In this latter case they can be identified as operations of the parent space group in its standard setting. |
