consider the following case where T is any matrix and P is the permutation matrix
we know that:
$T*T^-1=I$
now lets permute the matrix and multiply it with the inverse
$T*P*T^-1$
is there any way to calculate this multiplication faster? the fact that we know the T matrix (or T^-1) is permuted will help?
