FactInt is a GAP 4 package which provides routines for factoring integers, in particular:
- Pollard's p-1
- Williams' p+1
- Elliptic Curves Method (ECM)
- Continued Fraction Algorithm (CFRAC)
- Multiple Polynomial Quadratic Sieve (MPQS)
It also provides access to Richard P. Brent's tables of factors of integers of the form b^k +/- 1.
FactInt installs a better method for the operation Factors for integers.
For details see the package documentation in the doc subdirectory -- either
view its HTML version (chap0.html) with a browser, or its PDF version
manual.pdf with a PDF viewer.
This Version of FactInt needs at least GAP >=4.8.8 and GAPDoc >=1.6. It is completely written in the GAP language and does neither contain nor require external binaries.
Like any other GAP package, FactInt must be installed in the pkg/ subdirectory of the GAP distribution. This is accomplished by extracting the distribution file in this directory. By default, FactInt is autoloaded. This means that it is loaded automatically when you start GAP.
FactInt is distributed with the main GAP archive. For package updates between GAP releases itself check its web page https://gap-packages.github.io/FactInt.
