The IRREDSOL package Version 1.2 IRREDSOL is a GAP package which provides a library of all irreducible solvable subgroups of GL(n, q), up to conjugacy, where n is a positive integer and q a prime power satisfying q^n <= 1000000, and a library of all primitive soluble groups of degree at most 1000000. This version of IRREDSOL requires at least GAP 4.4.12. In order to install IRREDSOL, you have to get the package archive file `irredsol-1r2.tar.gz', or any other archive format suitable for your system. It is available for download from http://www.gap-system.org/Packages/irredsol.html To install IRREDSOL, move the package archive `irredsol-1r2' into the `pkg' directory in which you plan to install IRREDSOL. Usually, this will be the directory `pkg' in the GAP directory. If you already have a previous version of IRREDSOL, that is, there is a directory `irredsol' in the `pkg' directory, delete this directory first (or move it outside the pkg directory). You should now have a directory `irredsol' in the `pkg' directory. To load the IRREDSOL package manually, start GAP and type LoadPackage ("irredsol"); at the GAP prompt. If everything is ok, this should print a banner (if IRREDSOL is not already loaded) and return `true'.
