1 This definition agrees with that given by Fischer & Koch (1974)[link] and Koch & Fischer (1978)[link], but now the term Wyckoff position is used instead of Punktlage or point position, Wyckoff set instead of Konfigurationslage or configuration set, type of Wyckoff set instead of Klasse von Konfigurationslagen or class of configuration sets. New aspects have been taken into account by Koch & Fischer (1985)[link].
