The point groups are named according to their component symmetries. There are several standard notations used by crystallographers, mineralogists, and physicists. For the correspondence of the two systems below, see crystal system. In Schoenflies notation, point groups are denoted by a letter symbol with a sub… WitrynaHermann-Mauguin symbols, also known as international symbols, are oriented symbols giving the symmetry operations or symmetry elements of a point or space group. Three types of Hermann-Mauguin symbol are used: short, full and, for space groups, extended.
WitrynaThe characters appearing after the lattice letter in the Hermann-Mauguin (HM) symbol of a space group were originally meant to represent generating operations of the group. For instance, b was a b …

The four k subgroups with symmetry centres at 0, 0, 0 are Pmcb ( Pbam ); Pmna; Pbca; Pbnb ( Pccn ); those with symmetry centres at are Pbna ( Pbcn ); Pmca ( Pbcm ); Pmnb ( Pnma ); Pbcb ( Pcca ).
