http ://factordb.com/listtype.php?t=3&start=2402&perpage=100&mindig=553 times out, probably looping for a while (I ended up exceeding max CPU seconds per hour from my script retrying it repeatedly).
start=2502 works OK though. Note I've deliberately put a space into the URL so it's not a link in this post. You don't want to go there by clicking it. Chris |

I wanted to see how it looks like and narrowed it down more. The bad number is somewhere between skipping 2432 and 2442

It seems that above 150,000 digits, the only PRPs that FactorDB recognizes are for numbers constructed with powers of 10.
There are several large PRPs that are cofactors of Mersenne numbers (and of Wagstaff numbers and other generalized repunits), which cannot be recognized as such by FactorDB. For example the cofactor of 2^576551-1 |

I have asked for a way to upload RES64´s from PFGW some time ago.
I still thing it could be useful to allow some small amount of persons to upload these, to lower the amount of U´s. Also i have been thinking to import the whole TOP-PRP list into factordb, or link both. I have found some PRP´s (two tbh) that were already proven prime by certificate (round 10000 digits); those were now removed from TOPPRP. |

http://factordb.com/listtype.php?t=3...100&mindig=652 produces an incomplete web page with just the headings but no data.

Also broken from here. I pinpointed the problem to a single composite:

http://www.factordb.com/listtype.php?t=1 is broken. All I get is this (see attachment).
EDIT: I've narrowed it down to this: http://www.factordb.com/listtype.php...page=1&start=0 Last fiddled with by Stargate38 on 2019-07-22 at 21:08 Reason: narrowed down link |

The list of numbers with status unknown, http://factordb.com/listtype.php?t=2 has a problem at 26560 digits. I just get an incomplete web page with the headings but no data. 26561 digits works OK.

I've found 3 more places where I just get an incomplete page:
http://factordb.com/listtype.php?t=3...100&mindig=831 http://factordb.com/listtype.php?t=3...100&mindig=831 http://factordb.com/listtype.php?t=3...100&mindig=831 My script got http status "500 Internal Server Error" as well.
