Column pairs give the Schoenflies and equivalent international
notation. C indicates cyclic, D for Dihedral, S for
Spiegel (or 'mirror'), with h, v and d meaning
horizontal, vertical and diagonal (referring to
mirror plane locations.) A minus before a number indicates a
horizontal bar above that number. Brackets indicate equivalent
alternative.
