Quadrexommthet

Quadrexommthet is equal to \(f_{\theta(\Omega^4)}(10)\) 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 exactly equal to \(f_{\varphi(1,0,0,0,0,0)}(10)\), using Veblen function.
== Etymology ==
The 4 parts of the name, "quadri", "ex", "omm" and "thet", mean 4, exponentiation, \(\Omega\) and \(\theta\) function respectively, which form \(\theta(\Omega^4)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
