A Wieferich one is a number n such that n squared is congruent to one mod two to the quantity n minus one.
A Wieferich one is a number n such that n squared is congruent to one mod two to the quantity n minus one. A Wilson one is a number n such that n minus one factorial is congruent to negative one mod n squared. A Fermat one is a number n such that n is equal to two to the two to the m all plus one where m is a non-negative integer, and a Mersenne one is a number n such that n is equal to two to then m minus one, where m is, again, a non-negative integer. For ten points, identify these special cases of numbers that are divisible only by one and themselves.
