These tables of Cullen and Woodall numbers include factorizations for n up to 1000.   Cunningham Project - Current status of the project to factor numbers of the form b^n +/- 1, b = 2, 3, 5, 6, 7, 10, 11, and 12 maintained by Samuel S. Wagstaff.   Factor Tables - Richard Brent's tables extend the scope of the Cunningham project (factoring b^n+-1) to all applicable bases b less than 100, plus some higher bases.   Factorization Results - Tables, summaries, and links to many factoring endeavors, including primorials, factorials, and cyclotomic polynomials. Includes theorems and descriptions behind each project.   Factorization of Cyclotomic Numbers - Hisanori Mishima is coordinating the search and producing tables of factorizations of cyclotomic numbers for values of phi(n) less than 48.   Factorization of Generalized Repunits - Andy Steward's research into the form (b^n-1)/(b-1).   Factors - Lists the factors of every single number up to 600, for quick reference and as a resource for students.   Factors of 2^n + 1 - Factorizations for prime values of n up to 5000, extending the results of the Cunningham Project.   Fermat Factoring Status - Compiled by Wilfrid Keller, lists the known prime factors and complete factorizations of Fermat numbers.   Fibonacci and Lucas Factorizations - Tables of known factorizations of the first 10,000 Fibonacci and Lucas numbers.   Prime Factorization of Cyclotomic Numbers - Professor Mitsuo Morimoto extends the factor tables of cyclotomic numbers for values of phi(n) up to 120.   Smarandache Factors - Micha Fleuren's summary of the state of factorization of Smarandache and Reverse Smarandache numbers.
