Abstract: Two classes of natural symmetry constraints are introduced and analyzed for the Sharma–Tasso–Olver equation. Through those symmetry constraints, the phenomenon is exhibited that symmetry constraints do not always yield exact solutions. It is also explained why such phenomenon can happen in the symmetry theory.
