Zootzootplex is the exponential factorial of the googolplex, or \(\text{googolplex}^{(\text{googolplex}-1)^{(\text{googolplex}-2)^{.^{.^{.^{4^{3^{2^{1}}}}}}}}}\).[1] It was coined by Andrew Schilling at the age of four. In the hyperfactorial array notation zootzootplex can be expressed as \(\text{googolplex}!1\). It is less than and comparable to googolplexstack.
