    1440 <p class=MsoNormal><span class=GramE>k-SUBGROUPSMAG</span> operates by starting
    1441 with the grey group for the parent chemical structure (e.g. Pnma1’) and any
    1442 propagation vector (k-vector) by removing symmetry operators to generate
    1443 magnetic space subgroups. The remaining operators in each case are identified
    1444 with a standard setting of the known magnetic BNS space groups (2<sup>nd</sup>
    1445 setting with inversion at the origin as needed). It generally doesn’t stop
    1446 until the lowest possible symmetry (triclinic) is reached; there can be more
    1447 than 100 of these possible subgroups. For each one, the magnetic space group
    1448 symbol, lattice transformation matrix and any required translation of the
    1449 original coordinates is returned in a table of the results. In GSAS-II, the

    1452 page is parsed by GSAS-II to extract the generated magnetic space groups,

    1454 is orthorhombic, GSAS-II will by default transform the standard setting to a
    1455 setting where the unit cell axes orientation is preserved vs the chemical cell.

    1457 if any or all can carry a nonzero moment, flagging those space groups with
