Numbers of the form with a, b any coprime integers, a > b > 0, are called generalized Fermat numbers. An odd prime p is a generalized Fermat number if and only if p is congruent to 1 (mod 4). (Here we consider only the case n > 0, so 3 = is not a counterexample.) An example of a probable prime of this form is 124 + 57 (found by Valeryi Kuryshev). By analogy with the ordinary Fermat numbers, it is common to write generalized Fermat number…
