Section 3.4.3.5.1. Explanation of Table 3.4.3.4^{a}Institute of Physics, Academy of Sciences of the Czech Republic, Na Slovance 2, CZ18221 Prague 8, Czech Republic, and ^{b}Department of Mathematics and Didactics of Mathematics, Technical University of Liberec, Hálkova 6, 461 17 Liberec 1, Czech Republic 
The first three columns specify domain pairs.

The second part of the table concerns the distinction and switching of domain states of the nonferroelastic domain pair .
