The authors develop a modification of the method of asymptotic integration of Lienard systems and propose an analytical-numerical procedure making it possible to extend the domain of coefficients corresponding to the existence of a limit cycle in a quadratic system with a weak focus of order 3. The obtained result is interesting.
