  1. Mersenne Prime Digits and Names - Landon Curt Noll
    Tables of known Mersenne prime numbers: discovery dates, digit counts, decimal digits (American and European styles), English names, and English names with numbers. more>>

  2. Perfect Numbers - MacTutor Math History Archives
    Linked essay describing the work on perfect numbers from Pythagoras through Euclid, Nicomachus, the Arabs, Cataldi, Descartes, Mersenne, Fermat, Euler, Barlow, Catalan, Cole, and others; with other web sites and 20 references (books/articles). more>>

  3. Prime Curios! - G. L. Honaker, Jr., Chris K. Caldwell
    A collection of curiosities, wonders and trivia related to prime numbers. Look up a number (up to 10^21+) and find what connections it has to the primes. The database has over 3400 curios corresponding to more than 1960 different numbers. The number of entries increases as members of the mathematical community submit more information. more>>

  4. Prime Numbers - MacTutor Math History Archives
    Linked essay describing the work on primes from Pythagoras through Gauss, Legendre, Riemann, and Valee Poussin, with additional sections on still unsolved problems, the latest prime records, and other web sites, as well as 21 references (books/articles). more>>

  5. Prime Numbers - Math Forum, Ask Dr. Math FAQ
    What is a prime number? What's the 'Sieve of Eratosthenes'? What is the largest known prime? more>>

  6. The Prime Pages - Chris Caldwell; Dept. of Mathematics & Computer Science, Univ. of Tennessee at Martin
    An index of information on prime numbers. Definition; Articles and information on primes, including how to find and prove primality, and a wealth of historical information. Lists of primes and prime factorizations, including the first x primes and the largest known primes. Software Indexes and Programs; Archives and FAQ's; Miscellaneous links. more>>

  7. The Prime Puzzles & Problems Connection - Carlos B. Rivera
    An anthology of the most interesting problems and puzzles explicitly related to prime numbers. Organized into: Records (to convert you into a "prime hunter" - you'll discover that all you need to top a record is a PC, a good code, and a certain amount of patience); Conjectures (mathematical "guesses" that only the trained and skilled should try to tackle); Problems (amateurs may contribute work on these problems); and Puzzles (more than 30 puzzles having to do with prime numbers). more>>

  8. Puzzling Primes - Isaac Reed
    To fully comprehend our number system, mathematicians need to understand the properties of the prime numbers - but even finding them isn't so easy. more>>
