my number is bigger!

The rules are simple:

• no infinity
• no uncomputable functions
• no directly referencing the previous number
  We'll start with 9 instead of 9,999.

f₉(9)

f₉(9)^^f₉(9) (i hope this isnt uncomputable)

f₉(f₉(9)^^f₉(9))

f₉(f₉(9)^^f₉(9)) uu f₉(f₉(9)^^f₉(9))

I'm using the Ultrex formula thingamajig. Check the Wiki page on the Googology page.

f_{ψ₀(Ω_Ω)}(9)

f_lim(BMS) + psi(W_w)_(9)

f_{lim(MMS)+Y(1,3)+ψ(Ω_Ω)}(9999)

f_lim(BMS) + psi(W__w)^^w+1(9) where W__w means the limit of bucholz function

Not even close. MMS means Mutant Matrix System.

I don't know what any of these mean so I guess I'll just combine the last 2 together
(f_lim(BMS) + psi(W__w)^^w+1(9))^^^(f_{lim(MMS)+Y(1,3)+ψ(Ω_Ω)}(9999))

d^5(99)
