k is 10^3 | M is 10^6 | G is 10^9 | T is 10^12 |

Reserved | Available |

The Color of k indicates the different type of the number:

Low Weight k | Riesel Number k | 15k Candidate | 2145k Candidate | 2805k Candidate | Primorial k* |

(Note: 7911*2^15823-1 is also Woodall because it's the reduced form of 15822*2^15822-1 (only odd k)!!!)

(Note: three consecutive n like for k=3135 n=15,16,17 is called a Cunningham Chain of length 3 of first kind and so on...).

The

Numbers marked with 12345* got a

Twins upto n=15k calculated by Gary Barnes (see here)

05.12.2007 | Slightly changed menu structure, javascript for all pages imported from file |

25.11.2007 | New menu structure and extra pages for all 5 RPS-drives |

20.11.2007 | New Summary page with the even Riesel problem |

13.11.2007 | inserted k's from even Riesel problem (see here and here) |

28.10.2007 | new page with Riesel Problem with latest data |

24.10.2007 | new page with first odd k with twin |

Oct. 2007 | many small primes filled, mostly for ranges 10^4, 10^5 and 10^8 |

15.10.2007 | Inserted all Riesel-numbers where first prime n>16384, 358 numbers all over |

01.10.2007 | splitted k's in more files (for k<10k in 2k chunks, higher k's in 10^n chunks) so download-time is smaller |

13.09.2007 | new page with Statistics about primes, twins and Cunningham Chains |

Sept. 2007 | page with remaining k's filled with nash weights, colours for 15k and low weight k's; twins and Sophie Germain marked |

31.08.2007 | 784 twins for k<3009 marked |

09.08.2007 | marked some Twin primes for k's (Data from G.Barnes) not all yet; new Woodall Prime; Stats: all k's: 6588 k's with 116381 primes! |

07.08.2007 | k=8085 moved from remain-page to summary-page; included some riesel numbers with first prime from 200k to 250k (more to come) |

25.07.2007 | more than 630 new primes included since 12.07.2007: actual for k>300 there are 6362 k's with 110641 primes listed! |

22.07.2007 | new page with all contributors of RPS-Project with their prover codes and number of primes found |

18.07.2007 | new page with overview of all known Woodall-Primes (see here) |

15.07.2007 | included Primorials upto Pr(11) (next will follow) with their primes, Note: Primoproth has many false n, now ok in summary |

12.07.2007 | all k<10k with n<10k from gd_barnes included from here (new page with remaining k's) |

06.07.2007 | some errorfixes for k=1421,2683,7911,9225 and all Woodall-primes (thanks Gary Barnes) |

28.06.2007 | all k's, primes and reservations from PrimeSearch inserted in 300<k<3010 page |
