The numbers here constitute my supply of "interesting" numbers to use as test cases in my search for a better factorization algorithm. This factor table was begun on July 4, 1998. Latest update was on June 1, 2001.
The factors on this page are for numbers which have a single non-unit digit followed by some number of "1" digits. The compact notation used to represent these numbers is d(n) where d is the initial digit and (n) gives the number of ones that follow that digit. For example 5111111 would be written as 5(6).
If anyone is interested in factoring any of the unknowns listed here, feel free to email me your factors (fiziwig@yahoo.com), and I will credit you with any factorizations you find.
