Fugagoogolplex

Under left-association, a fugagoogolplex is equal to \(\text{googolplex} \downarrow\downarrow \text{googolplex}\) = googolplexgoogolplex(googolplex-1), or a googolplex raised to the googolplexth power googolplex-1 times.The Fz, The Fuga & The Megafuga - Large numbers site by Sbiis Saibian It is comparable to googoltriplex, but only on a googological scale - while a googoltriplex is 1 followed by a googolduplex zeros, one would have to raise a googolduplex to the power of approximately a googol to get the number of digits in a fugagoogolplex.
Alistair mentioned this number, and described how it can easily be ignored since his then-six-year-old son would just use gargoogolplex in lieu of the (slightly smaller in doubly exponential terms) googolplex.
