Orbifold GW theory as the Hurwitz–Frobenius submanifold

We study the relation between the Frobenius manifolds of GW theory and the Hurwitz–Frobenius manifold. We prove that the Frobenius manifold given by the orbifold GW theory of P1(2,2,2,2)P1(2,2,2,2) is isomorphic to the submanifold in the Hurwitz–Frobenius manifold of ramified coverings of the sphere by the genus 11 curve with the ramification profile (2,2,2,2)(2,2,2,2) over ∞∞.
