👉 In mathematics, a "hafter" is an element of a ring or module that satisfies certain properties. Specifically, it's a generator for the ideal generated by the ring or module under consideration. This means that any other element in the ring (or module) can be written as a product of hafters with respect to the given generators. For example, consider the ring of integers modulo 5, which is a finite field with 4 elements: {0, 1,
