User blog:MilkyWay90/The Kroutonillion

Since we've lost the Croutonillion, I feel we should have a Kroutonillion.

Start at \(X = \{\underbrace{9, 9, \ldots, 9}_{999999999999999999999999999999999999999999}\}\)

1. \(f_{\varphi^{X}(X, X, X, X, X)}(X)\)

Write down in the comments the next step (for example, 2. 2X, 3. {X, X, X, X, X})
