- A List of Prime Numbers - All of the prime numbers less than 2000000000.
www.rsok.com/~jrm/printprimes.html
- A Monte-Carlo Primality Tester - The factoring problem seems very hard. But to test a number for having factors turns out to be much easier than to find them. It also helps if we supply the computer with a coin-flipping device. We now consider a Monte Carlo algorithm, i.e. one that with high probability rejects any composite number, but never a prime.

- A Phyllotaxis Prime Number Sieve - A prime number sieve based on a daisy integer map. The sieving algorithm is demonstrated for a daisy with Fibonacci (21,34)-phyllotaxis using a three-dimensional diagram of a daisy capitulum and a two-dimensional spreadsheet.

- Testing for Primality - Since ancient times, mathematicians have been fascinated by problems concerning prime numbers, and many people have worked on the problem of determining ways to test if numbers are prime. One way to test if a number is prime is to find the number's divisors. The following program finds the smallest integral divisor (greater than 1) of a given number n. It does this in a straightforward way, by testing n for divisibility by successive integers starting with 2.
