Symmetry named by a letter and a subscript.
Also known as: Molecular symmetry notation, Point group letter notation
The older notation for symmetry groups, naming a group by a letter for its principal axis type and a subscript for its order and additional elements.
Names a symmetry group by a letter for its principal axis type and a subscript for its order.
Contexts: Laboratory
Names the group rather than listing its elements, which makes it shorter than Hermann-Mauguin and unable to express the translational symmetry a space group needs.
Contexts: Laboratory
Survives in spectroscopy and molecular chemistry, where translation does not arise, so the two notations divide by discipline rather than by date.

A capital letter followed by a subscript figure and sometimes a further letter, such as a letter D with a subscript.
