👉 In mathematics, a degeneracy is a concept that refers to the number of times a variable can be repeated within a function or system. In other words, it quantifies how many times a parameter (or set of parameters) appears in a given expression or equation. For example, consider the function f(x) = x^2 + 3x + 5. The degeneracy of this function is 1 because only one variable, x, can be repeated within the function.
