The correct prime factors are 6078346283854099769513887715088352414739207730274159525875618199 (64 digits) and 25881674549927780834661181082380297664708607029465684452103524592385640817740835852840616796345243365968651 (107 digits), see http://factordb.com/index.php?id=1100000007576206626 |

The prime factors in http://pastebin.com/M9z8HzfF (C171_660_1043) are 54259147160015513400521130420708460848245651210270483144839 and 1485336674563622718011814777176343851879921566164542790029380617285288221771774050680252756446835000234270486367, but when I report these two prime factors to factordb, it says that these two primes does not divide the “C171_660_1043” number (171 digits, 1573177803…3079079549, http://factordb.com/index.php?id=1100000007576206626), and the product of these two primes is a 170-digit “uninteresting” number (8059310120…8235909913, http://factordb.com/index.php?id=1100000007634345826), maybe the GNFS polynomial is wrong? |

Will the next numbers after 10,365+ be the quintic numbers 12,319- and 11,341- ? |

https://escatter11.fullerton.edu/nfs/numbers.php 7,395- is not P113*P201, it is P107*P114 |

Can you reserve all remain numbers with difficulty < 325? (i.e. 11,311+ 5,464+ 7,416+7,448+ 11,338+)? (7,448+ is reserved by Dodson for 6 years with no result) |

Now three numbers with exponents divisible by 5 (but not 3,7,13) are reserved, so what are their true difficulty? For 2,2350M, the SNFS suggestion difficulty is 283, and its true difficulty seems to be 324 (since it is reserved at this time, just after 11,311-, whose SNFS difficulty is 324), also 2,1180+ and 2,2390L, the SNFS suggestion difficulty are 285 and 288, respectively (also, why not reserve 7,395-? It is also exponent divisible by 5 and SNFS difficulty is 267, less than 2,2350M’s 283) |

How about 3,715-? 715 = 5*11*13, and the SNFS difficulty is 272.913, but as you say, exponents divisible by 5 or 11 is more difficult than their SNFS-size suggests, but exponents divisible by 3, 7, or 13 is not. |

So does the status of numbers list https://escatter11.fullerton.edu/nfs/numbers.php now includes all numbers with SNFS difficulty <= 324? |

Why just-factored 2,2622L (SNFS 264) is not shown in https://escatter11.fullerton.edu/nfs/numbers.php? Also, what is the current progress of 10,323+? |

Thanks! So 10,323- will not be completed in April? And 47.5% … so the currently progress of 10,323- is the same as the progress of which day of 5,461+? (see [url] https://pastebin.com/Awnh2MmT[/url]) Is about Apr. 1st? |

What is the currently progress for 7,889M? |

Message 2284 Posted 6 Mar 2022 by DSJR9453 |
So when 7,889M has 80% sieved, you will start 5,461+, and when 5.461+ has 80% sieved, you will start 10,323-? |

e.g. in https://kurtbeschorner.de/, this website shows that the currently progress for R1340L (10,670L in Cunningham table) is 36% What is the currently progress for 7,889L and 7,889M? Also, I think they should be done before Mar. 7th (am I right?) since see http://pastebin.com/Um73g3mH, 12.298+ was factoring only using 5 days (Feb. 5 to Feb. 9), and see https://pastebin.com/fFbkEYgD, 3.674+ was factoring only using 8 days (Jan. 21 to Jan. 28), and 7,889L was already factoring as of early February…. |

So only when exponent n is divisible by 3, 7, or 13, b^n+-1 has difficulty eulerphi(2*n)*log(b)/log(10) and is easier to factor? Otherwise (e.g. n is prime or 5*prime or 11*prime), b^n+-1 has difficulty n*log(b)/log(10) (more difficult than the SNFS difficulty when n is 5*prime or 11*prime)? |

5*prime should be also suitable, see https://www.rieselprime.de/ziki/SNFS_polynomial_selection Thus 7,395- and 7,395+ should be SNFS 264, and 10,365- and 10,365+ should be SNFS 289, like that 10,371- is SNFS 313, and 3,791- is SNFS 324 So 7,395-, 7,395+, 10,365-, 10,365+ should be already factored, but they are not …. |

Okay. Besides, can https://escatter11.fullerton.edu/nfs/numbers.php include all numbers with SNFS difficulty <= 325? (In the past this list includes many numbers whose “status†are neither “sieving†nor “queuedâ€, see https://web.archive.org/web/20210304225928/https://escatter11.fullerton.edu/nfs/numbers.php) https://homes.cerias.purdue.edu/~ssw/cun/who.txt says that all of them (except 11,341- and 11,311+) are reserved. |

Currently 12,298+ is done, and 7,889L is already sieving, but at any time there should be two numbers sieving, why 7,889M is not sieving? Do you forget it? |
