Septitetrep

Septitetrep is equal to \(f_{\varepsilon_0\uparrow\uparrow7}(10)\) 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 "ep", mean 7, tetration and \(\varepsilon_0\) respectively, which form \(\varepsilon_0\uparrow\uparrow7\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.

Notation 	Approximation
BEAF 	\(\{10,10((X \uparrow\uparrow X)^7) 2\}\)Using particular notation \(\{a,b (A) 2\} = A\ \&\ a\) with prime b.
Extended Cascading-E Notation	\(E10(\#\text{^^}\#)\text{^^}7\)
Hardy hierarchy 	\(H_{\varepsilon_0↑↑7}(10)\)
Slow-growing hierarchy 	\(g_{\vartheta(\varepsilon_{\Omega 2}^{\varepsilon_{\Omega + 1}↑↑6})}(10)\)
