Tetra-petaxis

The tetra-petaxis (formerly tetra-petaksys, also called dekataxiataxia-taxis) is equal to E1#1#1#4 = E1#1#10#3 in Hyper-E Notation. The term was coined by Sbiis Saibian. In up-arrow notation, this number is equal to \(10\uparrow\uparrow\uparrow\uparrow 4\) or 10 hexated to 4.
Username5243 calls this number toodcolduplex or tetooquol, and it's equal to 10[3]10[3]10[3]10 = 10[4]4 in Username5243's Array Notation.Part 1 - My Large Numbers
