A recently formulated nonlinear and electric-magnetic duality invariant extension of four-dimensional source-free Maxwell theory (ModMax) received a lot of attention. In this paper, the authors show that the already longer known six-dimensional nonlinear conformal chiral 2-form theory is related to the 4D ModMax theory by dimensional reduction. They study systematically exact solutions of this theory coupled to gravity (plane waves, black, strings, etc.) and their relation to supergravity solutions.
