In general, "degeneracy" means "reverting to an earlier, simpler, state"
In mathematics, a limiting case in which a class of object changes its nature so as to belong to another, usually simpler, class. See mathematical degeneracy.

ABSTRACT Degeneracy, the ability of elements that are structurally different to perform the same function, is a prominent property of many biological systems ranging from genes to neural networks to evolution itself.
Degeneracy is used to designate different wave function satisfying the same energy state in quantum mechanics.
Degeneracy, the ability of elements that are structurally different to perform the same function or yield the same output, is a well known characteristic of the genetic code and immune systems.
They collapse, moving down and to the left of the main sequence until their collapse is halted by the pressure arising from electron degeneracy.
Electron degeneracy is a stellar application of the Pauli Exclusion Principle, as is neutron degeneracy.
But even that is not the ultimate limit, since neutron degeneracy can also be overcome by masses greater than 3 solar masses and the ultimate collapse is toward a fl hole.
