The IRREDSOL package Version 1.1.2 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 < 2^16. This version of IRREDSOL requires at least GAP 4.4.7. In order to install IRREDSOL, you have to get the package archive file `irredsol-1r1n2.zoo', 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-1r1n2' 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'.
