Claim: The set of all maximal ideals in

is not in one-to-one correspondence with

.

I haven't found a proof yet. Seems that I have to show that the set of all maximal ideals in

is is less than 3 or greater than 3.

Ideas:

I can show that

is a maximal ideal using 1st Iso. Thm. and the fact that

is a field. I could probably show that

is a max ideal similarly; haven't done this yet as I'm not sure it helps. It might be true that these are the only maximal ideals of

but I'm not sure how to prove it. If these are true, then we're done.
