- Tables of maximal and minimal numbers with two, three or four prime factors of the same length (in decimal notation).
- 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, jr.
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.
- Tables, summaries, and links to many factoring endeavors, including primorials, factorials, and cyclotomic polynomials. Includes theorems and descriptions behind each project.
Factorizations of Repunit Numbers
- Tables available in text and compressed format.
- Lists the factors of every single number up to 600, for quick reference and as a resource for students.
