At this site we maintain a list of the 5000 Largest Known Primes which is updated hourly. This list is the most important databases at The Prime Pages: a collection of research, records and results all about prime numbers. This page summarizes our information about one of these primes.

This prime's information:

field (help) value Description: primA(41665) Verification status (*): PRP Official Comment: Lucas Aurifeuillian primitive part, ECPP Proof-code(s): (*): c8 : Water, Broadhurst, Primo Decimal Digits: 3211   (log10 is 3210.67543477) Rank (*): 55998 (digit rank is 1) Entrance Rank (*): 32121 Currently on list? (*): short Submitted: 7/29/2003 13:06:12 CDT Last modified: 7/29/2003 13:06:12 CDT Database id: 65687 Status Flags: Verify Score (*): 28.9117 (normalized score 0)

Archival tags:

There are certain forms classed as archivable: these prime may (at times) remain on this list even if they do not make the Top 5000 proper.  Such primes are tracked with archival tags.

Verification data:

The Top 5000 Primes is a list for proven primes only. In order to maintain the integrity of this list, we seek to verify the primality of all submissions.  We are currently unable to check all proofs (ECPP, KP, ...), but we will at least trial divide and PRP check every entry before it is included in the list.
