TFN

==Introduction==
 [Johndog69420]: Hey, you remember that one legendary difficulty called KLJY, Peak 23?
 [Kaan69]: Yeah, why?
 [Johndog69420]: Well, I was actually attempting it (not that it's hard) and I accidentally downloaded a new application.
 [Kaan69]: Well, what's it called?
 [Johndog69420]: TFN.app.

==What is TFN?==
===To be fair...===
TFN is the current last Peak 23 and the single most hardest one. It's comparably harder than both KLJY's first and second phase, and it's also its' sub difficulty. TFN has no current obstacles, because of its' sheer difficulty and hardness. Even trying to comprehend one word on its' hardness will probably result in your head spontaneously combust into a supermassive black hole. Yeah, that's how hard it is. So, you can choose. Either take this route, and shows as an estimate to how easy Class 24 is compared to the Ordinals, or skip to Aleph-Math.
===TFN itself===
TFN has a special property in which it can modify itself to be considerably easier than The First Difficulty, or harder than Über, but Jesus Christ only allowed the creator of TFN for itself to cap at Peak 23, to compare itself to an actual Class 24. So, your TFN could be harder than KLJY, and my TFN could be easier than N/A. But still, even with all these special properties, it still does not come close in even comparing with atleast 0.01% of TFinD. TFinD itself also has a special property, it simply defies logic. So, that's why this difficulty can't even come CLOSE with comparing with TFinD. So, practically, if you're astute enough, TFN could also mean The Finite Number. I consider difficulties above 12 to be inaccurate, because that of my definition of "unbuildable" is "physically AND mentally cannot build in normal studio". So even if your "Effortfulful" difficulty has EXPAN^INFINITY###MIFTEEN jumps, that could be, and it's theoretically possible to mentally build it in your head. One good example of "Near-Unbuildable" difficulties is PURE INSANITY, which utilizes that it's near-unbuildable by using your mental skill in order to do the obstacles.
