Hi, This comes from Griffiths Intro to Quantum Mechanics Prob. 4.2 We're asked to solve an infinite cubical well, which I have no problem with. The next part asks you to call the distinct energy levels E1, E2, E3... etc. in order of increasing energy and determine their degeneracies. It then asks what the degeneracy of E14 is and why is this case interesting. I think the degeneracy of E14 is 6, however I don't see why this case is interesting.
