The LieAlgDB Package -------------------- The package LieAlgDB provides access to several classifications of Lie algebras. In the mathematics literature many classifications of Lie algebras of various types have been published (we refer to the bibliography of the manual for a few examples). However, working with these classifications from paper is not always easy. This package aims at making a few classifications of small dimensional Lie algebras that have appeared in recent years more accessible. For each classification that is contained in the package, functions are provided that construct Lie algebras from that classification inside GAP. This allows the user to obtain easy access to the often rather complicated data contained in a classification, and to directly interface the Lie algebras to the functionality for Lie algebras which is already contained in GAP.

Usually, this will be the directory `pkg' in the hierarchy of your version of GAP 4. (However, it is also possible to keep an additional `pkg' directory in your private directories, see section "ref:Installing GAP Packages" of the GAP 4 reference manual for details on how to do this.) Then unpack the archive file and that's it! To use the online help, it is necessary to install the GAP4 package GAPDoc by Frank Luebeck and Max Neunhoeffer, which is available from the GAP site or http://www.math.rwth-aachen.de/~Frank.Luebeck/GAPDoc/. Bug reports ----------- If you encounter problems, please contact one of the authors. When sending a bug report, remember we will need to be able to reproduce the problem.
