RT Journal Article T1 On 2-abelian (n-5)-filiform Lie algebras A1 Campoamor Stursberg, Otto-Rudwig A1 Ancochea Bermúdez, José María AB We classify the (n − 5)-filiform Lie algebras which have the additional property of a non-abelian derived subalgebra. Moreover we show that if a (n − 5)-filiform Lie algebra is characteristically nilpotent, then it must be 2-abelian.
