**Determine the subgroups**

**Let S: = {(123),(235)} be a subset of $\sum_{5}$. Determine the subgroup <S> of $\sum_{5}$?**

What exactly is this asking? Is S the set of just two elements here? Or all elements containing these permutations? If the former how can S be a subgroup?

**Let G = <g> be a cyclic group of order 12. Find all subgroups of G.**

Again, I am not 100% clear on the notation and just want an idea of what to do. The terms seem so broad.

Gracias,
