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 (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.
