Tetra-taxis

The tetra-taxis (formerly tetra-teraksys, also called dekalogialogialogue) is equal to E1#1#4 in Hyper-E Notation. The term was coined by Sbiis Saibian. In up-arrow notation, this number is equal to \(10\uparrow\uparrow\uparrow 4\). It is equal to a power tower of a tria-taxis tens.
Username5243 calls this number Tetooquol, and it's equal to 10[4]4 in Username5243's Array Notation.
ARsygo coined deckerduplex for this number.AR Googol - Numbers from BEAF. Retrieved 2022-11-05.
