Jens Kruse Andersen's APTreeSieve

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)

APTreeSieve can sieve arithmetic progressions k*b + a with arbitrary a, b. It uses the GMP library and has sublinear speed in the size of a and b. However, it is not as fast as sieves written specifically for small a (e.g. +/-1) and b = base^n for small base.

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