Septitetrotos

Septitetrotos is equal to \(f_{\psi(I\uparrow\uparrow 7)}(10)\) using the fast-growing hierarchy and the fundamental sequences for a certain functions collapsing weakly inaccessible cardinals.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, "septi", "tetr", "ot" and "os", mean \(7\), tetration, the first inaccessible cardinal \(I_1\) and a certain function collapsing weakly inaccessible cardinals respectively, which form \(\psi(I\uparrow\uparrow 7)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
