👉 In mathematics, a "doublon" is defined as a pair of numbers that satisfy a particular condition. These conditions are usually given in terms of a specific mathematical operation or function. For example, if you have two numbers, \(a\) and \(b\), and the operation \(\oplus\) (or addition) is applied to them, then this operation will result in another pair of numbers that satisfy certain properties. For instance, consider the set of all positive integers, den
