My Factor Collection -- \(a^n\pm1\)



Introduction

This is a database of factors of numbers of the form \(a^n\pm1\). It is mostly just the larger Brent-Montgomery-te Riele set which runs from base 2 to 9999 and exponent 1 to 9999. There is also a smaller set for \(a^n < 10^{255}\) and 13 <= a <= 99.


Check out these other active overlapping DB sites:

Cunningham Project \(a^n \pm 1; a \in \{2, 3, 5, 6, 7, 10, 11, 12\}\)
GIMPS Project \(2^p - 1\)
ECMNET Project ecm factors >= 60 digits; Cunningham Project factors
Studio Kamada \(10^n \pm 1\)
FactorDB all factors (but use judgement when x-posting factors as it may be considered spam.)
