The correct symmetry of the six-fold twin in β-Ca11B2Si4O22

Abstract : A recently reported sixfold twin in beta-Ca11B2Si4O22 was interpreted as a transformation twin obtained during cooling of a hypothetical hexagonal high temperature phase. The suggested dichromatic symmetry of the twin is incorrect because 1) a sixfold twin cannot be represented by a dichromatic twin point group but by a hexachromatic group; 2) the reported dichromatic group does not exist. The correct hexachromatic twin point group is reported here.
