Herman-Mauguin notation

Phillips, F.C. (1972) An Introduction to Crystallography, 4th edition, Wiley, New York. Includes a clear description of the Herman-Mauguin notation and the 32 classes of crystal symmetry. First published in 1946. 

Symbols of point groups and space groups are based on two notation systems Schoenflies notation and Herman-Mauguin notation. 

We have already covered the symmetry elements that apply to individual molecules (in the Schoenflies notation) in Section 2.3.1, and you should read this section now if you have not already done so. We now need to consider the symmetry operations that map the relationships between entire arrays of atoms or molecules in three dimensions. These are generally expressed using the Herman-Mauguin symbols, in which the inversion operation, i, is replaced by 1, the reflection, [Pg.324]
