Comments:

NPD
Except for the unit cell parameters, position structure from a determination at 2K
Below 7K a commensurate structure with k=(1/4,0,0) is reported (see #2.38 and #1.1.78)
The MSSG also allows a sine modulation of the x component which is zero in the model

Comments (symmetry):

1k incommensurate structure
k-maximal magnetic symmetry (2 possible)
