If you wish to calculate commutators based on a Lie algebra (e.g. Heisenberg-Weyl one), there is a fancy way to implement it through a derived class from clifford. See for example my message http://www.ginac.de/pipermail/ginac-devel/2005-July/000793.html However for big powers it work very slowly and you may get much more exciting performance with the Singular package: http://www.singular.uni-kl.de/ Best wishes, Vladimir -- Vladimir V.
