Petommthet

Petommthet is equal to \(f_{\theta(\Omega_{10^{15}})}(10)\) using the fast-growing hierarchy and Feferman's \(\theta\)-function with this system of fundamental sequences. Also it is equal to \( f_{\psi_0(\psi_{10^{15}}^3(0))}(10)\) using the fast-growing hierarchy with fundamental sequences using equalities to outputs of Buchholz's function.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", "omm" and "thet", mean \(10^{15}\), \(\Omega\)-ordinals and \(\theta\) function respectively, which form \(\theta(\Omega_{10^{15}})\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
