First three fermat numbers
WebSince the first three double Fermat numbers 2 for n=0,1,2 i.e. 2 =5, F 1 F 2 2 =17, 2 =65537 are double Fermat primes but the third double Fermat number . F3 1 F 3 2 = 2 +1=F8 is not double Fermat prime, by Definition 7.4 we can confirm there exists an original continuous natural number sequence of double Fermat primes i.e. n = 0,1,2.

WebDefinition: When 2^2^n +1 is prime, it is said to be a Fermat number. The only known Fermat primes are the first five Fermat numbers: F0=3, F1=5, F2=17, F3=257, and F4=65537. A simple heuristic shows that it is likely that these are the only Fermat primes (though many folks like Eisenstein thought otherwise). 2. Algorithm WebIn 1638, Fermat proposed that every positive integer is a sum of at most three triangular numbers, four square numbers, five pentagonal numbers, and -polygonal numbers. …
