Abstract: We classify metabelian Lie algebras with successive dimensions of quotients of the lower central series ${\scriptstyle(m,n)=(5,5)}$ and ${\scriptstyle(6,3)}$. The problem is reduced to describing orbits of the linear group ${\scriptstyle \Ext^2\SL_m\otimes\SL_n}$, the latter being a ${\scriptstyle\theta}$-group in both cases. The results obtained in the paper allow to complete the classification of metabelian Lie algebras of dimension up to ${\scriptstyle 9}$.
