Figure 2
The point groups in both Hermann–Mauguin and Schoenflies notation as classified in ITA [Table 3.2.1.4 in ITA 6 (2016 )]. The entries in the first row and first column give the sequence of the groups in ITA. The cells of the centrosymmetric groups are shaded. This table differs from Table 3.3.1 in ITI (1952 ) (see the Supplementary Commentary) in the placing of the centrosymmetric groups with n odd. If the ITA table were constructed in the same way as the ITI table the centrosymmetric groups with n odd would be moved one column to the right. |
