No question was "what", i.e. give me some properties that left-to-right tetr. does satisfy which is not satisfied by right-to-left tetration, but which you would expect from a tetration. As nuninho already wrote you can replace the roots by logarithms for the right-to-left tetration of negative values, then however tet(-2) is not defined, but this is not really a drawback.

I don't know......... I'm guessing that with a series of numbers generated by left to right tetration there would be a easy to find out the nth term and with right to left tetration there wouldn't, but I haven’t tried that out yet.

It is not even true that (x^^y)^(x^^z) = x^^(y+z). One can prove that any suitable operation ^^ which satisfies this equation is trivial, e.g. x^^y=1. Neither left-to-right tetration nor right-to-left tetration nor symmetric/balanced tetration satisfies this anticipated property.

sorry I mistaked. I edit from "... X = oo" to "... X = -oo" in my post #6 and from x^(x^n) to "x^(x^(n-1))" in my post #8.
