    • Actually, the RT structure of Lasub 2CuOsub 4 is orthorhombic (D2h18). The T phase is achieved above 432 K.

    • There seems to be some confusion about the symmetry of the ground state that derives from the election of axes either along the tetragonal ones or along those of the pseudocube of oxygens around Pr, which are rotated 45° with respect to the former. This results in interchanging Γ 4 and Γ 3 representations. In the first case, as in Ref. 12, the ground state transforms as a Γ 3. In Ref. 10, though the parameter signs correspond to tetragonal axes, the level labeling of their Fig. reffig4(b) corresponds to cubic axes, so that the ground state transforms as Γ 4.
