Non-transposable domain pairs. (a) The parent phase with symmetry [G=6_z/m_z] is represented by a dotted hexagon and the three ferroelastic single-domain states with symmetry [F_1=F_2=F_3=2_z/m_z] are depicted as drastically squeezed hexagons. (b) Domain pair [({\bf S}_1,{\bf S}_2) ] and transposed domain pair [({\bf S}_2,{\bf S}_1)]. There exists no operation from the group [6_z/m_z] that would exchange domain states [{\bf S}_1] and [{\bf S}_2], i.e. that would transform one domain pair into a transposed domain pair.
