We report on Hall effect measurements in a Hg0.82Re0.18Ba2Ca2Cu3O8+delta su
perconductor. In the normal phase, the Hall coefficient is positive and var
ies with the temperature as (T + theta)(-1). Near T-c, and in fields below
mu H-0 = 2T, a double sign reversal of the Hall resistivity is observed. In
the regime approaching the zero resistance state, the Hall resistivity sca
les as a power law of the longitudinal resistivity.
