Abstract We derive an on-shell diagram recursion for tree-level scattering amplitudes in N $$ \mathcal{N} $$ = 7 supergravity. The diagrams are evaluated in terms of Grassmannian integrals and momentum twistors. generalising previous results of Hodges in momentum twistor space to non-MHV amplitudes. In particular. https://toyscyclers.shop/product-category/educational-toys/
