Solvable extensions of the naturally graded quasi-filiform Leibniz algebra of second type L2

For a sequence of the naturally graded quasi-filiform Leibniz algebra of second type L-2 introduced by Camacho, Gomez, Gonzalez and Omirov, all possible right and left solvable indecomposable extensions over the field are constructed so that the algebra serves as the nilradical of the corresponding solvable Leibniz algebras we find in the paper.
