|[A_{00},A_{11},A_{22}]| = \sum_{i=0}^2 |[A_{0,0+i \;mod\; 3},A_{1,1+i \;mod\; 3}]|A_{2,2+i \;mod\; 3}  \end{equation}  Therefore we can write the general formula \begin{equation}  |[A_{00},\dots,A_{nn}]| = \sum_{i=0}^{n-1} |[A_{0,0+i \;mod\; n+1},\dots,A_{n-1,n-1+i \;mod\; n+1}]|A_{n,n+i \;mod\; n+1}  \end{equation}
