I have attached a formula which contains 6 sums each ranging from 1 to n over a rational function.
The problem is that when I set n=5 the sum becomes too big and when I factorize the kernel shuts down stating that no more memory is left.
For n=2 n=3 and n=4 it does the job, and the final result, after factorization, is very simple. The same would be for bigger n.
I'm not very familiar with mathematica. Is there a way to rearrange the expression in order not to loose the memory?
Please find attached the computation I'm looking for. It's very important for me, so I'd be very grateful if you could help me.
