So I posted here the most solvable version of your question I could think of on MO http://mathoverflow.net/questions/262444...-functions
If this statement turns out to be true then it unequivocably proves that not only is the schroder iteration method the only completely monotone solution to tetration; but also for pentation, sexation, and so on. I'm confident this statement follows too. This would give a really good real valued criterion for the uniqueness of
for )
and 
. I hope someone in the more general mathematics community might be able to help us.
