Primes is a search tool for prime numbers. It allows you to
search primes in different manners, and can generate primes of very big
sizes (up to 200 digits or more).
For efficiency reasons, the tool will first give you lists of,
probable primes as search result
you can then click on the number to pass a rigorous
primality test on it. (Note however that you only have one chance over
billions to find a probable prime which is not prime.)
