Septinet

Septinet is equal to \(f_{\varphi(4,0)[8]}(10)\) using the fast-growing hierarchy and Veblen's function's fundamental sequences.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", "in" and "et", mean 7, the "in-" operation and \(\eta\)-ordinals respectively, which form\(\varphi\)\((4,0)[8]\) (i.e. 7 more insertions of \(\eta\)) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
