The symmetries of domain states of a domain pair (S1,S2) can be determined from the symmetry group F1 of the first domain state and a twinning operation g12 which transforms this domain state into the second. A classification is introduced which classifies all possible domain pairs according to a classification of the pairs F1 and g12. One obtains 139 classes of which 43 correspond to non-ferroelastic domain pairs and 96 to ferroelastic domain pairs. The tensor distinction of domain states of a domain pair is determined by the group F1 and g12 and all domain pairs belonging to the same class have the same tensor distinction. The 139 classes of pairs F1 and g12 are tabulated along with their corresponding twinning group K12 = < F1, g12 >, the group generated by F1 and g12. The tensor distinction of domain states of domain pairs of each class is given for a variety of material property tensors.
