# How to insert these matrices in Mathematica

I wanna ask how to insert these matrices in Mathematica when the dimension is (2N+6) by (2N+6). I think we can insert it if we can rewrite it as a block matrix where the entries are 2 by 2 matrices and then use "ArrayFlatten".

Thanks.

data = Array[a, {3, 2, 2}];

You merely have to replace the matrix data by $V_{m,1}$ etc.
