comment Degeneracies of the first excited state
Thanks, @Ted. Why is (2,2,2) nondegenerate? Can't we have, say (1,2,3)? I must be missing sth here...

comment Degeneracies of the first excited state
Thanks, Vladimir. I understand what degeneracy is, in principle. What I am unclear about is what qualifies as the first excited state -- if only one dimension is excited or whether all 3 are. Also, I don't know how many degeneracies there are.
