The Bretón–Manko equatorially antisymmetric binary configuration revisited

The Bretón–Manko solution for two identical counter-rotating Kerr–Newman charged masses is rewritten in the physical parametrization involving Komar quantities. The new form of the solution turns out to be very convenient for verifying that the black-hole sector of the Bretón–Manko binary configuration saturates a recent geometric inequality for interacting black holes with struts discovered by Gabach Clement.
