The Tricameron was comprised of a "Senate"—evenly divided against itself into a half that proposed and passed legislation, and a half that vetoed it—and a "Praetorate," a sort of quadruple troika or duodecimvirate: twelve men and women who implemented the Senate's decrees, declared war or peace, and (it seemed to Jim) spent most of the time squabbling amongst themselves for power.
