$$ Wall–Sun–Sun primes - $F_n$ are Fibonacci numbers and $\pi(p)$ is Pisano period. A Wolstenholme prime is a prime number $p > 7$ that satisfies the congruence The corresponding OEIS sequence is A088164.ĭefinition. The only known such primes are $16843$ and $2124679$, but it is believed (conjectured) that there are infinitely many. They have connections to Fermat's last theorem. Wolstenholme prime is a special prime number related to a stronger version of Wolstenholme's theorem. rev fL ) |> List.Take a look at the following two examples of "rare interesting primes" Printfn "The first 20 anti-primes are :-" for (_,g ) in ( List. takeWhile ( fun (_,_,n ) ->n fE n (fG g ) ) ( seq ) fI ) |> List.

If one of the problems is solved and accepted by the mathematics community, then they may be removed. If new, relevant conjectures are made, they may be added to this page. Integer procedure divisor_count( integer value v ) begin This page was created to organize all the conjectures and unsolved problems involving prime numbers, listed from highest to least importance. % calculates the number of divisors of v % % find some anti-primes - numbers with more factors than the numbers % Palindromicity depends on the base of the numbering system and its writing conventions, while primality is independent of such concerns. Output: 1 2 4 6 12 24 36 48 60 120 1 5040 7560 A palindromic prime (sometimes called a palprime) is a prime number that is also a palindromic number.
