Hectargum-quadrexom

is equal to \(f_{\omega^4}(100)\) using the fast-growing hierarchy.AR Googol - FGH Page 2 Retrieved 2024-09-13. The term was coined by wiki user . The number is comparable to quintoogol, and pentoogol.
== Etymology ==
The 2 parts of the name, "hectargum" and "quadrexom", mean applying 100 to the argument, which form \(\omega^4(100)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
