This category contains numbers that can be defined or estimated using fast-growing hierarchy in the form fα(n) with α in iterated Cantor normal form and reasonably small values of n, which is roughly equivalent to Jonathan Bowers' tetrational array.

The lower bound of this category is \(f_{\omega^{\omega^{\omega^{\omega^\omega}}}}(10^{10^6})\), and the upper bound is \(f_{\varphi(1,0)}(10^6)\).
