Phil Carmody's 'K' sieves

program

A titan, as defined by Samuel Yates, is anyone who has found a titanic prime. This page provides data on those that have found these primes. The data below only reflect on the primes currently on the list. (Many of the terms that are used here are explained on another page.)

Descriptive Data: (report abuse)

This is a suite of "fixed k" sieves designed to be portable over many architectures (x86, Alpha, PPC, HPPA, Sparc, Power, etc.) and operating systems (Windows, linux, *BSD (inc. OSX), HPUX, Solaris, AIX, etc.).
It incorporates:
'ksieve2', which can sieve many k values in parallel;
'NbeGone', a sieve for the Seventeen or Bust project,
'dlog', for Cunningham-project style factorisation tasks,
'ck' for (generalised) Carol/Kynea forms
'abc10' for 10a±b·10c±1 (includes near-repdigit forms and "just 1 and 0" forms)
(Note - for fixed-k sieving a single small k value on x86 (P4 in particular) machines running windows, Paul Jobling's NewPgen should be faster. Also investigate Mark Rodenkirch's 'multisieve' for some of the other forms, as his asm may be faster than my C.)

Error in data above: The HTML mark-up tag "r" is not allowed on these pages.

Surname: Ksieve (used for alphabetizing and in codes)
Unverified primes are omitted from counts and lists until verification completed.
