Q:

List the elements of G

So we are asked to write out the elements of G and H where G= $ \mathbb{Z}/ <20> $ and
H = $<4, 20>$ . I understand how to do H and I got: 
{$0 + <20>, 4 + <20> , 8 + <20>, 12 + <20>, 16 + <20>$ } from here through, would G=
{$1+ <20>, 2+ <20>, 3+ <20>$, etc....} or how do I find this???

A:

You are correct about both of them.
