Category talk:Prime numbers

Not for individual numbers
Category:Prime numbers is not for individual small numbers which happen to be prime. If a large number is only notable and has an article because it's a prime number then it may belong here. PrimeHunter (talk) 00:40, 21 June 2010 (UTC)

Soft or weak Primes
Category:Prime numbers I'm missing an Article about soft or weak Primes. The corresponding Page in the German wiki is:David Bruchmann (talk)10:40, 16 Februar 2011 (CET)


 * The English Wikipedia does not have such an article but making it is a good idea. It's listed at Missing science topics/Maths30 and a row at User:CRGreathouse/Tables of special primes. The first external link in the German article should be updated to http://people.missouristate.edu/lesreid/POW12.html. The German article says "Über die Endlichkeit ihrer Menge ist bisher nichts bekannt." I think this claims it is unknown whether there are infinitely many, but this is not true. Terence Tao proves the infinitude of weakly primes in any base in, and says Erdős had previously established it for base 10. By the way, I'm Jens Kruse Andersen mentioned at the end of the introduction in Tao's paper. At I found the titanic weakly prime (17×101000−17)/99+21686652 which I think is the largest known weakly prime. I may make an article Weakly prime within a day (and try not break WP:COI). It would belong in Category:Classes of prime numbers. PrimeHunter (talk) 17:54, 16 February 2011 (UTC)


 * I think it's probably a good idea to have such a page. I don't like the idea of putting it at Weakly prime which is an adjective, contrary to our Style Guide.  Weak prime or Weakly prime number would be fine. CRGreathouse (t | c) 06:48, 17 February 2011 (UTC)


 * I have created Weakly prime number and redirected Weakly prime. PrimeHunter (talk) 00:32, 18 February 2011 (UTC)
