WebThe sieve of Atkins is a modified version of the ancient prime number sieve of Eratosthenes. It applies a modulo-sixty arithmetic and requires less memory, but in R is not faster because of a double for-loop. In double precision arithmetic integers are represented exactly only up to 2^53 - 1, therefore this is the maximal allowed value. dangerous triangle in the oceanWebEdit: Also, I don't think that implementing the Atkin sieve is very useful for your purpose.
