$[Image: svg.image?f_%7B\omega-1%7D(x)]$ would a be a sequence, such that when applied x time to x it results in $[Image: svg.image?f_\omega(x)]$ . What about extending the Fast-growing hierarchy to other Hyperreals? such as omega minus 2?

Extending the Fast-growing hierarchy to things like $[Image: svg.image?f_%7B\omega-1%7D(x)]$ has already been discussed here.
