# p(122110618)

At this site we maintain a list of the 5000 Largest Known Primes which is updated hourly.  This list is the most important PrimePages database: 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:

Description: p(122110618) PRP Partitions, ECPP This prime has 1 user comment below. c77 : Batalov, Primo 12302   (log10 is 12301.277150387) 77152 (digit rank is 3) 66845 no 5/7/2015 00:06:12 CDT 5/7/2015 11:20:29 CDT 119885 338 Verify 33.0818 (normalized score 0)

#### Description: (from blob table id=338)

The number of unrestricted integer partitions of 122110618 is p(122110618).

#### 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.
Elliptic Curve Primality Proof (archivable *)
Prime on list: no, rank 206

 Primo certificate is available at FactorDB. numbpart(n) in Pari/GP is working well for sizes n ~ 10^8. For larger arguments, Arb implementation can be used. For example, the smallest (PR)prime partition number p(n) with n>=10^10 is p(10^10+76282) = 27994222743945352244...15765421425294386781 (111391 digits).

#### 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.
