We study the effect of Freudenthal duality on supersymmetric extremal black hole attractors in = 2, D = 4 ungauged supergravity. Freudenthal duality acts on the dyonic black hole charges as an anti-involution which keeps the black hole entropy and the critical points of the effective black hole potential invariant. We analyze its effect on the recently discovered distinct, mutually exclusive phases of axionic supersymmetric black holes, related to the existence of nontrivial involutory constant matrices. In particular, we consider a supersymmetric D0-D4-D6 black hole and we explicitly Freudenthal-map it to a supersymmetric D0-D2-D4-D6 black hole. We thus show that the charge representation space of a supersymmetric D0-D2-D4-D6 black hole also contains mutually exclusive domains. © 2017 World Scientific Publishing Company.
