This directory contains tables of factors of a^n +- 1
for a = 13, 14, ... , 99 (perfect powers excluded).

For example, the tables for 13^n - 1 are in table13m
and the tables for 13^n + 1 are in table13p.

n satifies the constraint a^n < 10^255.

All the table files can be obtained in one batch from tables.tar.gz
(get it in binary mode, then   gunzip < tables.tar.gz | tar xf -
to extract the tables on a Unix machine).

The file comps.gz contains 3228 composite factors of numbers of the above
form.  If you factor any of these, please let me know.  The composites are
sorted by increasing size but I suggest that you do not start attempts
to factor them from the beginning - if everyone does that too much effort
will be put into the numbers near the beginning of the list.  Better would
be to choose a random starting point in the list.

The file factors.gz contains 163,794 factors f of numbers a^n +- 1,
where a < 10000, n < 10000, and f > 10^9. For n <= 12 these are mainly
from the Cunningham tables, for 13 <= n <= 99 they are mainly from
the Brent-Montgomery-te Riele extension of the Cunningham tables,
for 100 < n < 1000 they are mainly from the tables produced by
Hisanori Mishima and Mitsuo Morimoto with additions from 
Pete Moore and Andy Steward.
 
In the parent directory there are files gzipexe.exe, rpb117*.*,
and rpb134*.* which may be useful.  See the contents file in that directory
for further information.
