List the cyclic subgrous of U(30).
To do this, I listed each possible subgroup of U(30) and then tested whether they are cyclic. A problem I ran into, though, is that <13> appears to be cyclic and <23> does, but the answer in the back of the book does not include them.
Has anyone else encountered this problem or know the solution? I will try to ask during office hours....
