3-dim irrep active (6 different types of spin arrangements with different MSGs are possible for this irrep, three of them are of maximal symmetry). The reported spin arrangement corresponds to a special direction of the irrep order parameter having maximal symmetry. It is not clear if the other two possible spin arrangements of maximal symmetry were also considered and crosschecked.
