Hi all, Thank you Matt for bringing up this issue.
Massimo Nespolo has been fighting for the correct description of structures, specially focusing on symmetry and proper terminology, for years (see his many articles on the misuse of lattice, sublattice, superlattice, etc). He has, as well, been educating crystallographers of all ages in symmetry concepts and use through IUCr's MaThCryst Commision and Internationa School on Fundamental Crystallograpy courses around the world. He'll probably be remembered by many as a Dick Marsh of symmetry. I guess it is the task of all us, crystallographers, to promote the correct use of terminology related to crystal structures, as suggested by IUCr conventions included in IUCr Dictionary and modern literature. https://dictionary.iucr.org/Main_Page Best wishes for all of you that, in a way or another have this as a special week in your calendars, and Happy New Year for all.
