The pseudoautomorphism group of P3 blown‐up at 8 very general points

Abstract We prove that the pseudoautomorphism group of a blow‐up of at 8 very general points is trivial. We also establish the injectivity of the Coble representation associated to blow‐ups of at general points, answering a question of Dolgachev–Ortland.
