'''Carol numbers''' and '''Kynea numbers''' are numbers of the form <math>(b^n-1)^2-2</math> and <math>(b^n+1)^2-2</math>, respectively, while '''Carol primes''' and '''Kynea primes''' are [[prime]]s of those respective forms. Named and originally studied by [[Cletus Emmanuel]] starting in 1995, the search for new Carol and Kynea primes is now coordinated in a [[MersenneForum]] thread, and the results are stored here on Prime-Wiki.

In the context of the Carol/Kynea prime search, a Carol number is a number of the form <math>(b^n-1)^2-2</math> and a Kynea number is a number of the form <math>(b^n+1)^2-2</math> (can be written also as 4<sup>n</sup> ± 2<sup>n+1</sup>-1). A Carol/Kynea prime is a [[prime]] which has one of the above forms. A prime of these forms must satisfy the following criteria:

A Carol/Kynea prime is a [[prime]] which has one of the above forms. A prime of these forms must satisfy the following criteria:
−
*b must be even, since if it is odd then <math>(b^n±1)^2-2</math> is always even, and thus can’t be prime.
+
*{{Vb}} must be even, since if it is odd then <math>(b^n±1)^2-2</math> is always even, and thus can’t be prime.
−
*n must be greater than or equal to 1. For any b, if n is 0 then (b<sup>n</sup>±1)<sup>2</sup> is equal to 1, and thus yields -1 when 2 is subtracted from it. By definition -1 is not prime. If n is negative then (b<sup>n</sup>±1)<sup>2</sup> is not necessarily an integer.
+
*{{Vn}} must be greater than or equal to 1. For any {{Vb}}, if {{Vn}} is 0 then <math>(b^n±1)^2</math> is equal to 1, and thus yields -1 when 2 is subtracted from it. By definition -1 is not prime. If {{Vn}} is negative then <math>(b^n±1)^2</math> is not necessarily an integer.
−
*b may be a perfect power of another integer. However these form a subset of another base’s primes (ex. Base 4 Carol/Kynea primes are Base 2 Carol/Kynea primes where <math>n \bmod 2 \equiv 0</math>). So it is not necessary to search these bases separately.

Carol numbers and Kynea numbers are numbers of the form [math]\displaystyle{ (b^n-1)^2-2 }[/math] and [math]\displaystyle{ (b^n+1)^2-2 }[/math], respectively, while Carol primes and Kynea primes are primes of those respective forms. Named and originally studied by Cletus Emmanuel starting in 1995, the search for new Carol and Kynea primes is now coordinated in a MersenneForum thread, and the results are stored here on Prime-Wiki.

Definitions

In the context of the Carol/Kynea prime search, a Carol number is a number of the form [math]\displaystyle{ (b^n-1)^2-2 }[/math] and a Kynea number is a number of the form [math]\displaystyle{ (b^n+1)^2-2 }[/math]. A Carol/Kynea prime is a prime which has one of the above forms. A prime of these forms must satisfy the following criteria:

  • b must be even, since if it is odd then [math]\displaystyle{ (b^n±1)^2-2 }[/math] is always even, and thus can’t be prime.
  • n must be greater than or equal to 1. For any b, if n is 0 then [math]\displaystyle{ (b^n±1)^2 }[/math] is equal to 1, and thus yields -1 when 2 is subtracted from it. By definition -1 is not prime. If n is negative then [math]\displaystyle{ (b^n±1)^2 }[/math] is not necessarily an integer.
  • b may be a perfect power of another integer. However these form a subset of another base’s primes (ex. Base 4 Carol/Kynea primes are Base 2 Carol/Kynea primes where [math]\displaystyle{ n \bmod 2 \equiv 0 }[/math]). So it is not necessary to search these bases separately.

Due to the form of these numbers, they are also classified as near-square numbers (numbers of the form [math]\displaystyle{ n^2-k }[/math]).

History

Carol and Kynea numbers were first studied by Cletus Emmanuel in 1995[1], who named them after personal acquaintances[2]. He searched these forms for primes up to the limit of 15000.

Starting in 2004, Steven Harvey maintained a search for this form. At this time Multisieve and cksieve were used to sieve these forms and PFGW was used to test for primality. The search went dormant in 2011 and was resurrected in 2015 by Mark Rodenkirch. Initially Multisieve was used, but then later on he wrote cksieve which would later become part of the Mtsieve framework.

On 2015-12-26 Mark opened a thread[3] for a coordinated search of Carol/Kynea numbers on MersenneForum, which continues to this day.

All data are now collected here using the information from the forum posts. Feel free to get an account and editing pages by yourself.

How to participate?

Reserving

  • Reserve your base(s)/range(s) in this thread.

Sieving

  • Use cksieve (from Mtsieve) and
    • run a new sieve by calling cksieve -b 12 -n 1 -N 10000 -P 1000000000 (for base=12, n-range=1-10000, max prime factor 109). The sieve file will be written to ck_12.pfgw.
    • rerun an old sieve by calling cksieve -P 1e12 -i ck_12.pfgw -o ck_12.pfgw -f factors.txt (for base=12, max prime factor 1012, input/output files given, storing factors to "factors.txt").

PRP testing

  • Use PFGW calling pfgw64.exe -f0 ck_12.pfgw (running candidates file for base 12, no further factoring).

Prime testing

After testing with PFGW higher probable primes will be written in "pfgw.log". These have to be checked prime by calling like pfgw64 -tp -q"(12^68835-1)^2-2".

Reporting

Once you have completed your range, report any primes found in this thread. Then report the completed range in the reservation thread and specify whether you will continue with the base or release it.
