Any questions or corrections can be directed to jason. But the value of k was never specied, so this proof holds for all values of k nite and innite.

## Solutions by Chapter

Thus every nonidentity element has innite order. It contains the identity, so it must contain at least one nonidentity element. Otherwise, everything is okay. You could learn a lot from this. And to be greedy, follow that up by, is there a better way to see it?
