Subgroups of $\mathbb{Z}^*_n$ [closed]
I am trying to write a code using SAGE to find all subgroups of $\mathbb{Z}^*_n$ where the elements of subgroups are elements of $\mathbb{Z}_n$.
To elaborate, when I am using the command .subgroups(), it returns the subgroups in generator-relator form and not as integers. Is there anyway to do it?
Looks like duplicate of https://ask.sagemath.org/question/57703/ See answer there.
Thank you. It was helpful.
