X and Y rotor components for polyhedra in a fitted configuration at 150  K, relative to their orientations in the ideal [\beta] phase. The distribution of the rotations of the polyhedra, relative to the average positions in the [\beta] phase, clearly shows the rotations about the [\langle 100 \rangle] axes by which the [\alpha] phase is derived from the [\beta] phase.
