Some interesting bits from the article:
Anon is credited as the first author in the paper
Computers are able to calculate superpermutations for n = 4 and n = 5 but not for anything beyond that.
Since the series in question has 14 episodes, it would take 93,884,313,611 episodes to see all possible combinations. Or roughly 4 million years of non-stop viewing.
Is this number the exact result or a lower bound ?
Lower. Another mathematician derived the proof for the upper bound.
Get started anon!
But one person can only see one order. Unless you erase your memory
You can watch it again in a different order.
This is mostly about minimizing the number of viewings. So for a 3 episode series you can get order ABC and order BCA in 4 viewings instead of 6 by watching in order ABCA.
Additional context for tge uninitiated: the series “The melancholy of Haruhi Suzumiya” was aired out of sequence intentionally, which is to say that the episide order is not the chronological order of events. The show is a masterclass of storytelling, presenting just enough information for the viewer to follow the plot while leaving you constantly guessing and inferring information, since you learn plot details at a different pace than the protagonist. The show never tells you the episode’s chronological place, but it can be determined through observation of details such as season, references to other events, etc.
Highly recommended for even non-anime fans, it’s a great sci-fi comedy/drama/mystery.
Thanks, the article piqued my interest and after hearing all this I might have to check it out.
Just dont h8 it
Is that different from this one I remember watching years ago? youtu.be/OZzIvl1tbPo
Note I’m not really… Good at math nor really understand it.
I’ll still watch an entertainer and someone good at what they do for entertainment either way.
Same here. Another math-centric channel that’s super interesting is Numberphile. Binged a lot of those

I hate how every article written about it seemed hell bent into trying to make it look like it was some random weeb who channeled his love for anime to come up with a proof when almost everyone in that thread was a mathematician and they were all aware of the Traveling Salesman problem and knew exactly what they were trying to prove. The board is literally called Science & Math.

Well, yeah, it’s 4chan, that’s a given. What I’m trying to say is that it wasn’t some Good Will Hunting situation. It was competent people doing what they do for a living.

I don’t personally think Anon knew exactly what he was trying to prove (otherwise he would have published the proof already), but it is definitely true that the problem was posted on a forum that specifically catered to people with the kinds of skillsets that would be capable of solving these problems. Most likely Anon probably just saw this as a simple math challenge without any deeper meaning

Everyone else in the thread was talking about the traveling salesman. I won’t completely rule out that he, personally, didn’t know because mathematicians are weird af, but it would be very strange.
