Abstract
We present a computer program to generate and solve the defining equat ions for grading preserving contractions of Lie algebras of any type, and their representations. The algorithm applies to any grading semi-g roup which is finite and Abelian. It can perform contractions of Lie a lgebras and/or representations for which the grading is either generic or not.
