# subgroup of unit group of number field (without calculating unit group)?

https://ask.sagemath.org/question/272...

There is a similar question in this link. But I want to know whether I can do this (without knowing the unit group). So, I have collected a list of elements (from another code), which will be generators of the subgroup I want to generate. What should I do?

You should provide your code with the construction of the elements.
