In case of monoclinic systems, we recognize the one symmetry plane, the (12)
plane and this leads to:

(2) |

Without loss of generality, and to simplify discussion, we now rearrange the
rows and columns so that the 6th lie between the 3rd and 4th,

(3) |

and the stiffness matrix is now in **block diagonal** form.
