The result arose in the context of a relation between finite-volume energies and $\\mathcal K_{\\text{df},3}$, derived to all orders in the perturbative expansion of a generic low-energy effective field theory. In this work we set aside the role of the finite volume and focus on the infinite-volume relation between $\\mathcal K_{\\text{df},3}$ and $\\mathcal M_3$.
