Petinep

Petinep is equal to \(f_{\zeta_0[10^{15}+1]}(10)\) 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, "peto", "in" and "ep", mean \(10^{15}\), the "in-" operation, and \(\varepsilon\)-ordinals respectively, which form \(\zeta_0\)\([10^{15}+1]\) (i.e. \(10^{15}\) more insertions of \(\varepsilon\)) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
