The ring Z60 is a field right?

So a list of all its ideals would be 0 and all the elements in Z60.

Is this correct?

And could someone just explain quickly what a homomorphic image is?

Thank you.

No, is it to a power of a prime? No it is not.

So a list of all its ideals would be 0 and all the elements in Z60.

(Note: I worked on this problem before when you posted it and it got a little messy by looking at all the possible ideal. What I was doing was finding all the cyclic subgorups of this ring because they need to be cyclic for the additive group is cylcic)
