yeah it kinda does, but its proven to be finite and ridiculously large so it works

[@zekejanczewski7275]

Yeah. Same here. I haven't been able to find a good explanation of it online. They are either like " You need 14 degrees in theoretical mathematics and two English degrees to understand this." Or parrot how fast this funtion grows. From what I can tell, the more trees you exhaust increases the number of more complicated trees with more options to hit in the future. If you want a function which is easier to prove but has the same sorta jig, the Google able term here is "Hydra Game"

[@gpt-jcommentbot4759]

But there is a roughly equivalent function on the Fast Growing Hierarchy: f_θ((Ω^ω)xω,0)(n) which is much faster growing than Graham's Function. Approximated by representing the TREEs as transfinite ordinals and comparisons between it and the weaker function tree(n) [no uppercase].

This is a comment about LaTeX If you want to continue making videos with manim which has the classic "maths" font, then I want you to research some conventions about when to use which symbols. For example, f(x) is usually written with an italic f and an italic x, which is the default, why? Because of the general rule of thumb "variables/changing things are in italics" This rule also makes standard text non-italic That's why I felt a bit odd when I saw you write 100 to the googol but with googol in italics. This rule applies most commonly to stuff like the sine and cosine and log functions, so sin(x) is written with an upright "sin" and an italic "x" But there's some debate when it comes to other common constants, like "e"; Euler's number, "π", "i"; the imaginary constant which is the(?) solution of i² = -1 Some write them upright because they are defined just like sin and cos and log But some write them in italics because there's many 'e's and 'π's and 'i's in formulas This comment is over.

All of that is wrong. f_{w^2}(64) is *far* larger than G64. It's not even close. The upper bound for G64 is f_{w+1}(64). Furthermore, TREE(n) has no official bounds. Though, it's supposedly not meant to exceed a growth rate of f_{LVO}(some reasonably large n). Finally, you did not even attempt to clarify "Theta", which I believe you are referencing feferman's theta function, and th(w^w) doesn't make any sense without a diagonalising function.
