Then of course in this new resolution I'm going to have direct sums of tensor products. In sage I'm working with CombinatorialFreeModule, there is a way to defining a direct sum over CombinatorialFreeModule_Tensor?
Thanks in advance.Tue, 19 Jun 2018 03:39:48 +0200https://ask.sagemath.org/question/42658/direct-sum-for-tensor-product-of-combinatorialfreemodule/
