The Sophus package is written to compute with nilpotent Lie algebras
over finite prime fields. Using thispackage, you can compute the
cover, the list of immediate descendants, and the automorphism group
of such Lie algebras. You can also test if two such Lie algebras are
isomorphic.
The immediate descendant function of the package can be used to
classify small-dimensional nilpotent Lie algebras over a given
field. For instance, the package author obtained a classification of
nilpotent Lie algebras with dimension at most 9 over F_2.

Installing the Sophus package
------------------------------
To install the Sophus package, move the archive file 'sophus.tar.gz'
into the `pkg' directory in which you plan to install
Sophus. 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 dothis.) Then unpack the archive file and that's
it!
Please remember that if you want to use Sophus then you'll also need
to install Version >= 1.2 of the AutPGrp package.
