WebA Fermat primeis a Fermat number which is prime. It is an open question as to whether there are infinitely many Fermat primes. Surprisingly, Fermat primes arise in deciding whether a regular n-gon (a convex polygon with nequal sides) can be constructed with a compass and a straightedge. Gauss showed that a regular n-gon is con- WebKummer shows that all primes up to 37 are regular but 37 is not regular as 37 divides the numerator of B 32 B_{32} B 3 2 . The only primes less than 100 which are not regular are 37, 59 and 67.More powerful techniques were used to prove Fermat's Last Theorem for these numbers. This work was done and continued to larger numbers by Kummer, …

WebIn number theory, Euler's theorem (also known as the Fermat–Euler theorem or Euler's totient theorem) states that, if n and a are coprime positive integers, and is Euler's totient function, then a raised to the power is congruent to 1 modulo n; that is Generalized Fermat primes. Because of the ease of proving their primality, generalized Fermat primes have become in recent years a topic for research within the field of number theory. Many of the largest known primes today are generalized Fermat primes.

WebAlthough he claimed to have a general proof of his conjecture, Fermat left no details of his proof, and no proof by him has ever been found. His claim was discovered some 30 years later, after his death. This claim, which came to be known as Fermat's Last Theorem, stood unsolved for the next three and a half centuries.
