  Global results are proved about the way in which Boyland's forcing partial
order organizes a set of braid types: those of periodic orbits of Smale's
horseshoe map for which the associated train track is a star. This is a special
case of a conjecture introduced in a previous paper, which claims that forcing
organizes all horseshoe braid types into linearly ordered families which are,
in turn, parameterized by homoclinic orbits to the fixed point of code 0.
