But I also understand "superfunction", so I suppose it is a matter of taste.

But I think the terminology we agree upon is e.g. superexponential.

So superfunction is just a generalization of this terminology if we dont apply it to the exponential, but something else that perhaps has not a name.

One could also say inverse Abel function, but this is somewhat lengthy.

Btw. "orbit" is anyway wrong because its a set not a function.
