1 Replacing time inversion [1'] by an operation of `changing two colours', the two-colour groups corresponding to the types 1, 2, 3a and 3b magnetic groups are known as type I, II, III and IV Shubnikov groups, respectively (Bradley & Cracknell, 1972[link]).
2 In Litvin (2013[link]) the terminology `non-magnetic' is used in place of `non-primed' in the column headings in these tables.
