Millilogue is a base googolism of the second order Hyper-L notation invented by Googology Wiki user JTOnstead20. It is defined as \(L((6))\) in the notation. This means the following: Take the reverse Log function of 6 to get 1,000,000. Then use the double parenthesis to build a power tower starting with \(10^{1,000,000^{1,000,000^{...}}}\) and going a million units high. This is roughly equivalent to \(1,000,000\uparrow\uparrow 1,000,000\) in arrow notation.
