Petaddunep

Petaddunep is equal to \(f_{\varepsilon_1+10^{15}}(10)\) 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 4 parts of the name, "peto", "add", "uni" and "ep", mean \(10^{15}\), addition, 1, and \(\varepsilon\)-ordinals respectively, which form \(\varepsilon_1+10^{15}\) when concatenated backwards (where "uni" and "ep" form \(\varepsilon_1\)). So the full name indicates the ordinal index of the FGH.
