Giginep

Giginep is equal to \(f_{\zeta_0[10^9+1]}(10)\) using the fast-growing hierarchy.My system of number names (FGS) - Traveling To The Infinity The term was coined by wiki user Denis Maksudov.
== Etymology ==
The 3 parts of the name, "gigo", "in" and "ep", mean \(10^9\), the "in-" operation, and \(\varepsilon\)-ordinals respectively, which form \(\zeta_0\)\([10^9+1]\) (i.e. \(10^9\) more insertions of \(\varepsilon\)) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
