In this paper, we prove that all finite groups having at most three strongly monolithic characters are solvable. We also give some criteria for nilpotency of finite groups by their strongly monolithic characters. Finally, we classify all finite groups whose nonlinear irreducible characters are monolithic, exactly two of which are strongly monolithic.
