This excellent metasite for prime numbers is mind-boggling, not only in terms of the quality of information provided, but also in the breadth and variety of the hyperlinks, from discourse on the Riemann hypothesis to programs and freeware for calculating Mersenne primes. Dr. Chris Caldwell, creator of the Graph Theory Tutorial Website (discussed in the April 28, 1999 Scout Report for Science and Engineering) of the University of Tennessee at Martin, has provided local as well as external links to prime number research, records, and resources. Sections at this site include Primers, Articles, Information on Primes, Lists of Prime Numbers and Prime Factorizations, Software Indexes and Programs, Archives and FAQs from Related Areas, and a section entitled Gallimaufry (visualizations, special uses, and prime number puzzles). Students of all levels as well as professional mathematicians with an interest in prime numbers will find this one-stop shop an outstanding resource.
