Prime Pages
From Wikipedia, the free encyclopedia
The Prime Pages is a website about prime numbers maintained by Prof. Chris Caldwell at the University of Tennessee at Martin.
The site maintains the list of the "5000 largest known primes", selected smaller primes of special forms, and many "top twenty" lists for primes of various forms. As of December 2006, the 5000th prime has around 77000 digits.
The Prime Pages has a wealth of articles on primes and primality testing. It includes "The Prime Glossary" with articles on hundreds of glosses related to primes, and "Prime Curios!" with thousands of curios about specific numbers.
The database started as a list of titanic primes by Samuel Yates. For years the whole top-5000 has consisted of gigantic primes. Primes of special forms are kept on the current lists if they are titanic and in the top-20 or top-5 for their form.
