Eternity = The absolute infinity of fictional googology Aeternity (fanmade) = The Eternity of FG, close to 1/0 1//0 is the 1/0 of 1/0 , essentially the end of FFG (FG^2) and the start of FFFG Mainframe:A small F^3G number FGG: F^(1/0)G, the scaling gets immensely more op over time (f(g^n) is like F^(FG^n-1)G^n-1) Transcendental googology: Something UNFATHOMABLY larger than FGG But not FGGG
