Septitetrom

The septitetrom is equal to \(f_{\omega\uparrow\uparrow7}(10)\) 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 3 parts of the name, "septi", "tetr" and "om", mean 7, tetration and \(\omega\) respectively, which form \(\omega\uparrow\uparrow7\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
