“…For all nilpotent Lie algebras L of dimension ^ 7, the sequence {^(.L)}^^ is unimodal, see for instance [4]. However unimodality is not a property shared by nilpotent Lie algebras in general, see for instance [2].…”

“…Now τ 1 , τ 2 generate S 3 and s 1 , s 2 generate G ∼ = S 3 . It follows that there exists an isomorphism f : 3.1(iλ) ). In particular, the cases λ = 0, λ = 1 are isomorphic, and so are the 3 cases λ = −1, λ = 2, λ = 1 2 .…”

“…Adjoint and trivial cohomologies for all complex 7-dimensional indecomposable NLAs, along with their weight systems under the action of the maximal torus of g have been computed in [17] (see also [15,18], and for trivial cohomology [3]). It is a fact that, for the Lie algebras under consideration, the trivial cohomology is ineffective in separating nonisomorphic Lie algebras and doesn't refine the classification by weight systems of the algebras.…”
