Abstract: An isometric immersion of a Riemannian manifold $ M$ into a Riemannian manifold $ \overline M $ is called helical if the image of each geodesic has constant curvatures which are independent of the choice of the particular geodesic. Suppose $ M$ is a compact Riemannian manifold which admits a minimal helical immersion of order $ 4$ into the unit sphere. If the Weinstein integer of $ M$ equals that of one of the projective spaces, then $ M$ is isometric to that projective space with its canonical metric.
