hey guys thanks a lot for your help, after combining what you both said, I understand how the order of a^4 is 60. I have been doing some work on a few others and have come up with an order for a^60 as being 4. a^14 being 120. And a^57 having an order of 240..Do these seem correct to you guys?

Yes.

In general, if a has order n, then a^k has order n/(gcd(n,k).
