If this is too conflictprone, maybe using the prefix `cartesian_` suggested by Simon would be a solution? 20 22 21 There are also `summand_embedding()` and `summand_projection()` methods in `CombinatorialFreeModule_CartesianProduct`. Thatis OK if and only if there are only finitely many summands/factors; in that case the product and sum coincide, since modules form an additive category.23 For products of modules (the last two methods in the above list), calling the components "summands" is OK if and only if there are only finitely many summands/factors; in that case the product and sum coincide, since modules form an additive category. 22 24 23 25 > Also, I would like something different from ``factors'', since we will
