List of fermat primes
WebThe first result on the distribution of primes is Euclid’s the orem (circa 300 B.C.) on the infinitude of the primes. In 1737 Euler went a step further and proved that, in fact, the series of the reciprocals of the primes diverges. In the opposite direction, Euler observed that the rate of divergence of this Web28 mrt. 2024 · All Primes (1 mod 4) Equal the Sum of Two Squares.
