Query: Double Soft Limit of Graviton Amplitude from the Cachazo-He-Yuan
  Formalism   We present a complete analysis for double soft limit of graviton scattering
amplitude using the formalism proposed by Cachazo, He and Yuan. Our results
agree with that obtained via BCFW recursion relations in arXiv:1504.05558. In
addition we find precise relations between degenerate and nondegenerate
solutions of scattering equations with local and nonlocal terms in the soft
factor.
