Fermat
n. Pierre de Fermat (1601-1665), matematico francese, il primo ad applicare il calcolo differenziale nella ricerca delle tangenti. Condivise con Pascal la scoperta del calcolo delle probabilità.

Definitie
Fermat prime
<mathematics> A prime number of the form 2^2^n + 1. Any
prime number of the form 2^n+1 must be a Fermat prime.
Fermat conjectured in a letter to someone or other that all
numbers 2^2^n+1 are prime, having noticed that this is true
for n=0,1,2,3,4.
Euler proved that 641 is a factor of 2^2^5+1. Of course
nowadays we would just ask a computer, but at the time it was
an impressive achievement (and his proof is very elegant).
No further Fermat primes are known; several have been
factorised, and several more have been proved composite
without finding explicit factorisations.
Gauss proved that a regular N-sided polygon can be
constructed with ruler and compasses if and only if N is a
power of 2 times a product of distinct Fermat primes.

Fermat number
In mathematics, a Fermat number, named after Pierre de Fermat, who first studied them, is a positive integer of the form
where n is a non-negative integer. The first few Fermat numbers are:
- 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, ... (sequence A000215 in the OEIS).
If 2k + 1 is prime and k > 0, then k must be a power of 2, so 2k + 1 is a Fermat number; such primes are called Fermat primes. As of 2023, the only known Fermat primes are F0 = 3, F1 = 5, F2 = 17, F3 = 257, and F4 = 65537 (sequence A019434 in the OEIS); heuristics suggest that there are no more.
