recog

A GAP package for group recognition

Installation

To get the newest version of this GAP 4 package download the archive file recog-x.x.tar.gz and unpack it using

tar xvf recog-x.x.tar.gz

Do this in a directory called pkg, preferably (but not necessarily) in the pkg subdirectory of your GAP 4 installation. It creates a subdirectory called recog.

This is all which is needed if you installed the package in the standard pkg subdirectory.

Note that the recog package needs the AtlasRep, FactInt, Forms, genss, and orb packages to work.

If you installed the package in another pkg directory than the standard pkg directory in your GAP 4 installation, then you have to add the path to the directory containing your pkg directory to GAP’s list of directories. This can be done by starting GAP with the -l command line option followed by the name of the directory and a semicolon. Then your directory is prepended to the list of directories searched. Otherwise the package is not found by GAP. Of course, you can add this option to your GAP startup script.

Recompiling the documentation is possible by the command gap makedoc.g in the recog directory. But this should not be necessary.
