But having this way a (non-trivial) vector of different exponents (or better: bases) which comes out to be a meaningful "nested exponentiation" I'm curious, whether one can do something with it, for instance weighting, averaging, or multisecting that sequence of exponents/bases when re-combining them to a "nested exponential". We have not yet many examples of "nested exponentiations" with a meaningful outcome.

X_n^^[n] = y ( n = m in value )

For instance, the construction of the Schroeder-function is based on (ideally) infinite iteration of the base-function to get a linearization. If we iterate the h2()-function infinitely, the curve of the consecutive values in an x/y-diagram (where x is the iteration number) approach a horizontal line; don't know whether using that linearization shall prove useful for something similar.

(When Euler found his version of the gamma-function, that was in one version putting together sequences of integer numbers weighting and repeating in a meaningful way; there is some infinite product-representation for his gamma-function I think I recall correctly... )

(see also the updates in my previous (introducing) posting)

This reminds me of one of my posts on the OEIS many years ago , also under the pseudo tommy1729 ( i have other pseudo too ).

Go to Oeis and enter tommy1729.

Or use this link:

In particular

In abuse notation this becomes

(1 + 1/n)^^

And it was a special case of my investigations in the Tommy-Zeta functions between 2001 and 2009 given by

(1+1^(-s))^(1+2^(-s)) ...

This is somewhat similar and thus might intrest you.
