SUMMARY
The discussion centers on calculating the degeneracy of the 14th energy level in a cubic well, specifically identifying it as 4-fold degenerate. The energy states are represented as E_n = E(n_x, n_y, n_z), with E(3,3,3), E(5,1,1), E(1,5,1), and E(1,1,5) all yielding the same energy value. The participant highlights the relationship between degeneracy and symmetry, noting that double degeneracy corresponds to a 90-degree rotational symmetry. Additionally, there is clarification regarding the energy level definitions, emphasizing that n_x^2 + n_y^2 + n_z^2 = 14 does not correspond to the 14th energy level but rather to the 6th.
