Abstract
We consider the Moyal deformation of self-dual gravity. In the conformal primary basis, holomorphic collinear limits of the amplitudes of this theory show that it enjoys a perturbatively exact symmetry algebra that generalises , the loop algebra of the wedge algebra of , which appears in self-dual gravity.
