Symétrie ponctuelle (Fr). Punktsymmetrie (Ge). Simetria punctual (Sp). Simmetria del sito, simmetria puntuale (It).
The point symmetry of a position is its site symmetry. The point symmetry, or point group of a lattice is the group of linear mappings (symmetry operations, isometries) that map the vector lattice L onto itself. Those geometric crystal classes to which point symmetries of lattices belong are called holohedries.
