User blog comment:SuperSpruce/What do you think the growth rate of the Meameamealokkapowwa oompa is?/@comment-5150073-20190420062648

MO was considered to be "approximately" \(f_{C(C_1(\Omega)C_1(C(C_1(\Omega)99+9))+9)}(10)\) in terms of "catching functions" by Hyp Cos.

Catching function is related to \(\psi\) like so:

\(C(\varepsilon_0\omega) &=& \psi(\psi_{\Omega_{I+1}}(I))\)
