Terexommthet

is equal to \(f_{\theta(\Omega^{10^{12}})}(10)\) using the fast-growing hierarchy and Feferman's \(\theta\)-function.My system of number names (FGS) - Traveling To The Infinity The term was coined by wiki user Denis Maksudov.
It is equal to \(f_{\varphi(1,\underbrace{0,0,...,0}_{10^{12}+1\text{ 0's}})}(10)\) using Veblen function.
== Etymology ==
The 4 parts of the name, "tero", "ex", "omm" and "thet", mean \(10^{12}\), exponentiation, \(\Omega\) and \(\theta\) function respectively, which form \(\theta(\Omega^{10^{12}})\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
