Which quantum numbers must be the same for the orbitals that they designate to be degenerate in a many-electron system?

For the orbitals that designate to be degenerate in a many-electron system, the following quantum numbers should be equal:

1 - principle quantum number (n) : this describes the most probable distance of the electron from the nucleus

2 - o rbital angular momentum quantum number (l) : this determines the shape of the orbital
