Petinzet

Petinzet is equal to \(f_{\eta_0[10^{15}+1]}(10)\) 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 "zet", mean 1015, the "in-" operation and \(\zeta\)-ordinals respectively, which form \(\eta_0\)\([10^{15}+1]\) (i.e. 1015 more insertions of \(\zeta\)) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
