N2 - In this paper, we continue the study of abelian subalgebras andideals of maximal dimension for finite-dimensional supersolvable andnilpotent Lie algebras. We show that supersolvable Lie algebras withan abelian subalgebra of codimension 3 contain an abelian ideal withthe same dimension, provided that the characteristic of the underlyingfield is not two, and that the same is true for nilpotent Lie algebraswith an abelian subalgebra of codimension 4, provided that the char-acteristic of the field is greater than five.
