A beautifull day, I used a different sieve algorithm than the sieve of Eratosthenes. More under http://de.wikipedia.org/wiki/Benutzer:Bhelmes/Sieb_des_Helmes Sorry that it is only on German.
Have a look at http://www.devalco.de/Mersenne_liste.htm I checked 14*10^9 primes for the first 1000 Mersenne numbers and found for 40% a factor. This was only a test. I will try to improve the sieve by using 3 polynoms, which covers all primes. If you are interested have a short look at http://www.beablue.de/Primzahl/ Best greetings from the primes Bernhard -- www.devalco.de www.beablue.de Tel.: 0241 / 99 77 55 22 in Germany (0049) GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.
