Macaulay2 package GradedLieAlgebras -- A package for doing computations in graded Lie algebras. This package provides routines for doing computations in graded Lie algebras. The package relies on algorithmic theory on graded Lie algebras developed by Clas Löfwall and Jan-Erik Roos in A Nonnilpotent 1-2-Presented Graded Hopf Algebra Whose Hilbert Series Converges in the Unit Circle, Adv. Math. 130 (1997), no. 2, 161–200. See also the earlier implementation in Mathematica by C. Löfwall, Liedim, a Mathematica program for Lie-calculations (2001-2016), available at http://www2.math.su.se/liedim/
