There’s also that 4chan anon who made significant contribution to a math problem in order to find the best way to watch an anime
I miss when there were genuinely good posts on 4chan
I was very active from around 2003-2009, and I agree. I haven't been there in a loooong time but I imagine it’s absolutely terrible now.
Sometimes i wish i was autisitically smart
More details on this?

Lower bounds of superpermutations on this wiki page: https://en.wikipedia.org/wiki/Superpermutation
Please link this story
Lower Bound on the Length of the Shortest Superpermutation aka "The Haruhi Problem" by Anonymous
Video explaining the problem and solution
tl;dr if you have the numbers 1 and 2 you can make two permutations with them: 12 and 21. You can also make a "Superpermutation" with something like 1221 which is a sequence that contains all permutations of 1 and 2. A shorter sequence would be 121 or 212. Finding the shortest sequence that contains all permutations of any given set of numbers was an unsolved math problem. Someone posted on 4chan's anime board asking for the most efficient way to watch every permutation of "the endless 8", which are 8 nearly identical epsiodes of The Melancholy of Haruhi Suzumiya. Anime nerds pride themselves on watching these episodes over and over. Someone posted a sequence with a math proof for why it is the shortest. In essence, they posted the shortest superpermutation for a set of 8. The method can be used on any sized set and doesn't just apply to sets of 8.
Looks like this one https://en.wikipedia.org/wiki/Superpermutation based on the content of the wikipedia article
I’d also love to see this.
