Please see FAQ 6.2: https://www.gap-system.org/Faq/faq.html#6.2 on how to deal with memory limits (your error message corresponds to the "exceeded the permitted memory (-o command line option)" error listed there.) Given that the error happens in the calculation of a cartesian product, I suspect that you are asking for the creation of an unneccessarily large object: - Can you estimate before-hand how many elements would be in the product you calculate? How much memory would it take? Is this a plausible calculation for the computer you have? - Could you replace the creation of a full cartesian product by iterated for-loops over smaller products -- i.e. test product elements as soon as they are created, instead of storing all?
