g=generators(L)
The optional input given above is not relevant for Lie algebras. Instead of generators one may use the abbreviation gens.
i1 : F=lieAlgebra{a,b,c} o1 = F o1 : LieAlgebra
i2 : I=lieIdeal{a a b,a a c} o2 = I o2 : FGLieIdeal
i3 : L=F/I o3 = L o3 : LieAlgebra
i4 : gens L o4 = {a, b, c} o4 : List
