1/0 is the slope of a Thurston obstruction with c = 1 and d = 1.
These NET maps are not rational.
SLOPE FUNCTION INFORMATION

There are no more slope function fixed points.
Number of excluded intervals computed by the fixed point finder: 199
No nontrivial cycles were found.
The slope function maps some slope to the nonslope.
If the slope function maps slope s to a slope s' and
if the intersection pairing of s with 1/0 is n, then
the intersection pairing of s' with 1/0 is at most n.
The slope function orbit of every slope whose intersection
pairing with 1/0 is at most 50 ends in either the
nonslope or one of the slopes described above.
