These Thurston maps are NET maps for every choice of translation term.
They have degree 5. In fact, they are Euclidean.
PURE MODULAR GROUP HURWITZ EQUIVALENCE CLASSES FOR TRANSLATIONS
{0} {lambda1,lambda2,lambda1+lambda2}
These pure modular group Hurwitz classes each contain
infinitely many Thurston equivalence classes.
The number of pure modular group Hurwitz classes
in this modular group Hurwitz class is 5.

Every slope function orbit other than the two fixed points is infinite.
FUNDAMENTAL GROUP WREATH RECURSIONS
When the translation term of the affine map is 0:
NewSphereMachine(
"a=(2,5)(3,4)",
"b=**(1,5)(2,4)",
"c=(1,5)(2,4)",
"d=(2,5)(3,4)",
"a*b*c*d");
When the translation term of the affine map is lambda1:
NewSphereMachine(
"a=(1,2)(3,5)",
"b=(2,5)(3,4)",
"c=(2,5)(3,4)",
"d=(1,2)(3,5)",
"a*b*c*d");
When the translation term of the affine map is lambda2:
NewSphereMachine(
"a=(1,4)(2,3)",
"b=(1,5)(2,4)",
"c=****(1,5)(2,4)",
"d=****(1,4)(2,3)",
"a*b*c*d");
When the translation term of the affine map is lambda1+lambda2:
NewSphereMachine(
"a=(1,5)(2,4)",
"b=(2,5)(3,4)",
"c=(2,5)(3,4)",
"d=****(1,5)(2,4)",
"a*b*c*d");
