how can I write two "for do" loops which one of them is inside the other

hi In tensors, I want to calculate covariant derivative of a tensor of rank (1,1) but if found some erors in maple outputs whit (cov_diff) so I m trying to write a progeam with "for circle" for calculating covariant derivative. Please, help me to figure it out.


I have two unkhnown matrices. I intruduce one of them with fill:


I have a program with system of equations in wich my equations are in 8 matrices (4x4) with 64unknown parameters

i have run it but after 10 minitutes maple gives this massage:

"length of output exceeds limit of 1000000"

is there any way to solve this problem?



I have some equations like these:
