<h3>Abstract</h3>
<p>This package provides access to the classification of the following families of Lie algebras:</p>
<ul >
<li ><p>non-solvable Lie algebras over finite fields up to dimension 6;</p>
</li >
<li ><p>nilpotent Lie algebras of dimension up to 9 over <var class="Arg" >GF(2)</var >, of dimension up to 7 over <var class="Arg" >GF(3)</var > or <var class="Arg" >GF(5)</var >;</p>
</li >
<li ><p>simple Lie algebras of dimensions between 7 and 9 over <var class="Arg" >GF(2)</var >;</p>
</li >
<li ><p>the classification of solvable Lie algebras of dimension at most 4;</p>
</li >
<li ><p>the classification of nilpotent Lie algebras of dimensions at most 6.</p>
</li >
</ul >

<h3>Acknowledgements</h3>
<p>We are grateful to Andrea Caranti, Marco Costantini, Bettina Eick, Helmut Strade, Michael Vaughan-Lee. Without their help, interest, and encouragement, this package would not have been made. We also acknowledge the effort of the referees to improve the implementation and the documentation.</p>
<p>Serena Cicalò would like to thank the Centro de Álgebra da Universidade de Lisboa for their kind hospitality during July - December 2009 and May - September 2010, when the classification of the 6-dimensional nilpotent Lie algebras over fields of characteristic 2 was made and added to the package.</p>
