Note: the correspondence between contracted Greek indices and the Cartesian vector components used in Sections 3.1.3 , in the present chapter and in the software GIKoBo1, is defined in the following way:
In this designation, coefficients with contracted indices 4, 5, 6 appear two times, e.g. index 4 replaces yz in one coefficient and zy in the other coefficient. With this convention, the coefficients transform in tensor space as vector components, but some coefficients differ from the usual matrix notation (Voigt matrices) by numerical factors [see Section 1.1.4.10 ; Nye (1985); Sirotin & Shaskolskaya, Appendix E (1982)].
