16. The reflection indexed as (302) by Kusaba et al. (Ref. 12) is clearly indexed correctly as (013) in our patterns.
17. Kusaba et al. (Ref. 12) propose that the monoclinic shear is in the basal plane, but that is inconsistent both with the space-group symmetry—for a NiAs-like structure—and also with a strong contraction along the NiAs C axis.
18. The a-glide relates atoms (Formula presented) apart in the FeS-III structure, and this corresponds to atoms related by the a-glide operation plus a lattice repeat along (Formula presented) in the MnP structure, i.e., (Formula presented)

20. Refinement of a mixed-phase pattern at 7.1 GPa gives (Formula presented) (Formula presented) (Formula presented) for the MnP phase, and (Formula presented) (Formula presented) (Formula presented) (Formula presented) for the FeS-III phase. The volume difference of 6.7(2)% is smaller than found in Ref. 8, but agrees with Ref. 12.
