These Thurston maps are NET maps for every choice of translation term.
They have degree 12. They are imprimitive, each factoring as a NET map
with degree 6 followed by a Euclidean NET map with degree 2.
PURE MODULAR GROUP HURWITZ EQUIVALENCE CLASSES FOR TRANSLATIONS
{0} {lambda1} {lambda2} {lambda1+lambda2}
These pure modular group Hurwitz classes each contain only
finitely many Thurston equivalence classes.
However, this modular group Hurwitz class contains
infinitely many Thurston equivalence classes.
The number of pure modular group Hurwitz classes
in this modular group Hurwitz class is 24.
ALL THURSTON MULTIPLIERS c/d IN UNREDUCED FORM
0/2, 0/6, 1/6, 1/2, 2/2
Every NET map in these pure modular group Hurwitz classes
is rational because every loop multiplier in the
modulo 2 correspondence graph is less than 1.

SLOPE FUNCTION INFORMATION
There are no slope function fixed points.
Number of excluded intervals computed by the fixed point finder: 590
No nontrivial cycles were found.
The slope function maps some slope to the nonslope.
The slope function orbit of every slope p/q with |p| <= 50
and |q| <= 50 ends in the nonslope.
If the slope function maps slope p/q to slope p'/q', then |q'| <= |q|
for every slope p/q with |p| <= 50 and |q| <= 50.
