Category:Bachmann's collapsing level

This category contains numbers that can be defined or estimated using fast-growing hierarchy in the form fα(n) with α made from Bachmann's ordinal collapsing function and reasonably small values of n.

The lower bound of this category is \(f_{\varphi(1,0,0)}(10^6)\), and the upper bound is \(f_{\psi(\varphi(1,\Omega+1))}(10^6)\).
