comment Memory leak in simple program
I know that I am going to mutliply n! matrices and that it is a lot, but I am sure that Mathemica can handle mutliplying 3x3 matrices no? Maybe there is a more clever way of doing that

How Do I copy/paste a large output in a nice form?

I did restart the kernel as well as reboot the computer. Maybe I should reinstall Mathematica

comment Explicitly construct tensor quantities with given symmetries
Thank you very much for your answer. Sadly I cannot make it work with my MMA. While running the command makeSymmetricTensors[{a, b, c, d}, GenSet[Cycles[{1, 2}], Cycles[{3, 4}]]], I get a list of errors of the form ToCanonical::noident: Unknown expression not canonicalized: makeGSTensor[TakeList[{a,b,c,d},{2,2}]] . Would you know how to solve this ?

comment Explicitly construct tensor quantities with given symmetries
Thank you very much for your answer. It still requires a fair amount of work to know which kind of term can be written and how to symmetrize them, but it already helps a lot.

Map it to an expansion of a quantity that I know to fix the 6 constants.

comment Summation of Kronecker deltas should give the dimension
Thank you for your update. I am reluctant to do it symbolically as many part of the code depend on that sort of computation and are easier to solve with proper vectors.
