1 The Sophus Package 2 ------------------ 3 4The Sophus package is written to compute with nilpotent Lie algebras 5over finite prime fields. Using this package, you can compute the 6cover, the list of immediate descendants, and the automorphism group 7of such Lie algebras. You can also test if two such Lie algebras are 8isomorphic. 9 10The immediate descendant function of the package can be used to 11classify small-dimensional nilpotent Lie algebras over a given 12field. For instance, the package author obtained a classification of 13nilpotent Lie algebras with dimension at most 9 over F_2. 14 15 16 Authors 17 ------- 18 19The Sophus package was written by: 20 21Csaba Schneider 22Informatics Laboratory 23Computer and Automation Research Institute 24The Hungarian Academy of Sciences 251518 Budapest 26Pf. 63 27Hungary 28Email: csaba.schneider@sztaki.hu 29WWW: www.sztaki.hu/~schneider 30 31 Installing the Sophus package 32 ------------------------------ 33 34To install the Sophus package, move the archive file 'sophus.tar.gz' 35into the `pkg' directory in which you plan to install 36Sophus. Usually, this will be the directory `pkg' in the hierarchy of 37your version of GAP 4. (However, it is also possible to keep an 38additional `pkg' directory in your private directories, see section 39"ref:Installing GAP Packages" of the GAP 4 reference manual for 40details on how to do this.) Then unpack the archive file and that's 41it! 42 43Please remember that if you want to use Sophus then you'll also need 44to install Version >= 1.2 of the AutPGrp package. 45 46 Bug reports 47 ----------- 48 49If you encounter problems, please report them via our issue tracker: 50 <https://github.com/gap-packages/sophus/issues> 51 52When sending a bug report, please to to include enough information so 53that we can reproduce the problem. 54
