Query: Circle actions on 6-dimensional oriented manifolds with 4 fixed points   In this paper, we classify the fixed point data (weights and signs at the
fixed points), of a circle action on a 6-dimensional compact oriented manifold
with 4 fixed points. We prove that it agrees with that of a disjoint union of
rotations on two 6-spheres, or that of a linear action on $\mathbb{CP}^3$. The
former case includes that of Petrie's exotic action on $\mathbb{CP}^3$.
