Qwertycube

The Qwertycube is a cube that holds $$5 \uparrow \uparrow 57$$ Miniqwertycubes.

We define a function $$f(x) = f(x-1)^{f(x-1)}$$ where $$f(0) = 2$$, just like in the Qwertyverse. Using this simple function, Qwerycube 's size is precisely $$\overbrace{f(f(f( \cdots f(f(93,000,000,000)}^{93,000,000,000}$$.

Qwerycubes hold many Miniqwertycubes, because Miniqwertycubes contain resources that are used for building very large structures.
