    Description / Table of Contents: Zusammenfassung Es wird ein REDUCE-Programm zur Bestimmung der Symmetrien beliebiger Systeme von partiellen Differentialgleichungen beschrieben. Es kann sowohl interaktiv als auch im Batch-Betrieb verwendet werden. In vielen Fällen findet es die volle Symmetriegruppe vollständig automatisch. In einigen anderen Fällen bleiben einige lineare Differentialgleichungen des bestimmenden Systems übrig, dessen Lösung im Augenblick nicht automatisch gefunden werden kann. Falls sie vom Benutzer eingegeben werden, antwortet das System mit den infinitesimalen Generatoren der Symmetriegruppe.
    Notes: Abstract A REDUCE package for determining the group of Lie symmetries of an arbitrary system of partial differential equations is described. It may be used both interactively and in a batch mode. In many cases the system finds the full group completely automatically. In some other cases there are a few linear differential equations of the determining system left the solution of which cannot be found automatically at present. If it is provided by the user, the infinitesimal generators of the symmetry group are returned.
