I am co-author of several external GAP<\/a> packages. In order to browse through the manuals, you may just follow the links below, which direct you to the respective packages homepages. To use the packages, you must have a working copy of GAP with version number 4.5 or higher. In this case, you have probably already obtained the packages as part of the GAP distribution.<\/p>\n

I am also maintainer of these packages.<\/p>\n

Mathematical software plays many times an important role in the reasoning that ultimately leads to the proof of a theorem. The extensive consideration of examples usually benefits from computational means. But once a theorem is proved, one may ignore these means. Anyway, some authors like to provide some recognition… Pointers to some papers citing packages for which I am co-author may be found in my google scholar<\/a> page.<\/p>\n
