Ferroics with vector order parameters. This table summarizes how vector order parameters change their signs under space inversion and time reversal symmetry operations. Note that space inversion and time reversal symmetries are not broken in ferro-rotational order, while both of them are broken in ferro-toroidal order. Ferro-rotational order is sometimes called ferro-axial or electric ferro-toroidal order
