In CHY formalism, scattering equations map the kinematic space of Mandelstam invariants to the points on CP1. Recently Cachazo, Early, Guevara and Mizera have introduced generalization to the scattering equations on higher dimensional projective spaces, CPk-1. Bi-adjoint scalar amplitude is a well studied example of this generalisation. We study double soft limits of the generalised bi-adjoint scalar amplitudes for k=3.
