### Re: Ordinals in googology

That wasn't the question-- the question is whether that's the limit of Madore's psi Then BHO is the supremum of Madore's psi, and what the heck is ψ(Ω_ω) No Then I don't understand. The BHO = ψ(ψ_1(0)) Now everything has become clear for me Or is it? Madore's psi C(a) set includes ordinals in the f...

### Re: Ordinals in googology

I searched one more source http://quibb.blogspot.com/2012/03/infin ... tions.html

and it also says the BHO is ψ(Ω^Ω^Ω^Ω^...) = ψ(ε_Ω+1).

But it says that ψ1(0) = ε_Ω+1 (which is uncountable), not ψ(ε_Ω+1). Is that a mistake?

### Re: Ordinals in googology

Oh, whoops. The Bachmann-Howard ordinal is not in madore's psi but in weirmann's theta. Sorry. Yeah, psi(w_w) > psi(e_(W+1)) The Wikipedia artivle about OCF's says that the Bachmann-Howard ordinal is the supremum of psi(W), psi(W^W), psi(W^W^W), psi(W^W^W^W)... and we can't go any further with the ...

### Re: Ordinals in googology

I literally wrote that since the limit of Madore's psi is the Bachmann-Howard ordinal, psi(w_w) is no larger than the Bachmann-Howard ordinal. With Madore's psi, a>b does not mean that psi(a) > psi(b). It just means psi(a) >= psi(b). So in other words, psi(w_w) = the Bachmann-Howard ordinal. So why...

I meant f_w_1CK(n) in the fast-growing hierarchy. Yes, I said it would make sense if you have a fundamental sequence for w_1ck and then explained a possibility What is ψ(Ω_ω)?

I had 2 more questions in the previous post. Does the function f_w_1CK(n) make any sense? Yes, theoretically. But only if you have a fundamental sequence for w_1CK--which is still possible. E.g. w_1ck[n] = min a > all ordinals definable in n symbols in some language like set theory, or something e....
