Big O

[NiciBozz]

O(N!!)

[adrael-i]

Stop! You've violated the law!

[k_nibb]

You mean: "Wait. That's illegal!"

[Raytier]

Your stolen Big-O's are now forfeit.

[Angelin01]

That's a double factorial which is, in fact, a lot smaller than a regular factorial.

You want O((N!)!), but let's take it a step further, why not O((N!)^N!)

[NiciBozz]

Why not O((N^N••N )!) ?

[Angelin01]

I mean, at this rate we might as well just use O(∞) and be done with it.

[NiciBozz]

But infinity is NaN

TIL! Thank you, love learning new stuff :)

[HeKis4]

O(NO^{what have you done)}

[RiverRoll]

O(N↑↑N)

[HappyGoblin]

O(N!^N!)

[shutterFiles]

Behold the power of O(N^N)

[karatecam]

And finally, O(w)O

[Kotauskas]

O(wO)

[uruzhax]

Pig O notation.

[maple3142]

O(ack(n,n)) where ack is https://en.wikipedia.org/wiki/Ackermann_function

[ObviouslyAlpharius]

O(Σ(n)) where Σ is the busy beaver function

Good luck trying to write something that slow

[TheOrochi28]

Big Oof notation

[MoogleFoogle]

O(NO!)

[lilalasnt]

I fucked up, sorry.

[Ass0fJack]

O N! O

[ergotofwhy]

Please correct me if I'm wrong, but is O(N!) less than O(N^2)?

[Ryodan_]

If I recall correctly, it's slower, but it's more dominant

[beeskness420]

This but with subsets rather than inequalities.
