Hi Fellows, I have bugged now the ultimate authorities including Howard Flack (of Flack parameter fame), and alas, there is no official descriptive adjective for these 65 Söhnke space groups. Chiral is definitely wrong, and so is enantiomorphic, although 22 of the nameless form 11 enantiomorphic pairs. Thou shallst not use those descriptors for SGs, only for structures.
So the contest for a proper descriptive adjective is still open. Best, BR PS: Otherwise it is a bit like saying 'You know, that thing, the one where you see stuff moving and it is not black and white' instead of simply 'color TV' <- almost as old as space groups....
