## Main Question or Discussion Point

This isn't a homework question, rather a question about something stated in my book and an online source.

When is there degeracy in a 3-D rectangular box when none of the sides are of equal length?

I understand that when there are two or more state functions that have same energy level there is degeneracy... but more general, I read something online about the ratio of quantum numbers n must be equal to and integer (yet not equal to eachother), and/or there must be a linear combination of the lengths of the sides (i.e a=.5*b=.25*c, a being length in x, etc.)

Can someone better explain this to me?

As always, thanks in advance!
