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.
- Euler Irregular primes (archivable *)
- Prime on list: yes, rank 13
Subcategory: "Euler Irregular primes"
(archival tag id 215085, tag last modified 2023-10-06 17:37:13)- Elliptic Curve Primality Proof (archivable *)
- Prime on list: no, rank 566
Subcategory: "ECPP"
(archival tag id 215086, tag last modified 2024-10-27 10:37:10)
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.
