X and Y rotor components for polyhedra in a fitted configuration at 1073  K, relative to their orientations in the ideal [\beta] phase. The distribution of orientations has become isotropic about zero and is very broad, indicating the large amplitude of rigid-unit motion of the polyhedra. There is no evidence for the formation of domains of the [\alpha] phase.
