r12.4 is calculated as

\frac{r _{24} - r _{21} r _{14}}{( r - r _{12}^{2} ) ( 1 - r _{11}^{2} )}

\frac{r _{12} + r _{13} r _{24}}{( 1 + r _{13}^{2} ) ( 1 - r _{24}^{2} )}

\frac{r _{13} - r _{12} r _{24}}{( 1 + r _{12}^{2} ) ( 1 - r _{24}^{2} )}

\frac{r _{13} - r _{14} r _{24}}{( 1 - r _{14}^{2} ) ( 1 - r _{24}^{2} )}
