The Hall symbols for describing unambiguously the generators of space groups have been extended to describe any setting of the 1651 types of magnetic space groups (Shubnikov groups). A computer program called MHall has been developed for parsing the Hall symbols, generating the full list of symmetry operators and identifying the transformation to the standard setting.

将晶体空间群的霍尔符号扩展为磁性空间群

用于明确描述空间组生成器的霍尔符号已扩展，以描述1651类型的磁性空间组（Shubnikov组）的任何设置。已经开发了一种名为MHall的计算机程序，用于解析霍尔符号，生成对称运算符的完整列表以及识别对标准设置的转换。
