Generating the prime numbers by building successive wheels

WebIn mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit.. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant … Web5 Pritchard, P. A sllblinear additive sieve for finding prime numbers. Commun.
