 | Hello. It’s me, the hairy man in the video. Sadly I don’t have much progress to report since this was filmed at the end of October. I managed to improve the 4chan lower bound by one, but I think it’s fair to say we’re pretty stuck again after a period of rapid progress and wild optimism. We still haven’t been able to bring the upper bound down by one, but I still reckon it should be possible. I’m hoping someone here will have some good ideas! Комментарий от : @RobinHouston |

 | This is incredible, just one question as a non mathematician. To my understanding, 4chan didn't really solved it right? More like it became a draft for the formula Robin made but then the other guy made another one that had nothing to do? What was the concrete discovery 4chan made and does it still holds for today?

 | To give slightly more context of why that was even being discussed in 4chan: There is this highly popular classic anime called The Melancholy of Haruhi Suzumiya (yes, that one with the dance). This show was released in a particular order during the original TV airing, as to make sure the climax of the story was closer to the end, ignoring chronological events. But then for the DVD release the studio decided to change the order of the episodes to the cronological one. Not satisfied, in the re-releases, there was one with the first half chronological and the second as released in the TV airing, and then another airing where the made the opposite with the first half in release and second half in chronological. Not just that, but fans made their own watch orders as to highlight some aspect of the show. From this some guy asked how long would it take to watch ALL possible combinations and the discussion escalated from that. Комментарий от : @ggwp638BC |

 | I feel like I don’t understand the reasoning behind how the minimal superpermutation for n = 3 is constructed. It seems like a pattern is that you typically start with ABC…n, then write ABC…(n-1) where n is the nth symbol and so on. But then from there I’m not sure how you keep going or how to apply it to n = 4 case. Комментарий от : @josueramirez7247 |
 | If you're here for the 4chan bit, it's 12:14. Thank me later Комментарий от : @wombatpandaa9774 |
 | I feel like these would be better visualised in dimensions. when looking at the original expansion ab you mirror it, to get the alternate, -1. the original character you are ignoring. when adding the third character if you could add it in another dimension how would that look. rather than ABC C AB and count the permutations as dimensional mirrors this makes sense then of the n-1 format for presenting the data. Basically you'd be looking at something similar to the holographic principle where 3d data can be represented on a 2d sheet and I would expect it continues. I'm probably drawing connections that don't actually work for someone who knows the topic better. Комментарий от : @kosgoth |

Super perms with the Super perm! no... He knows a thing or two about 'super PERMS' no... Ugh I should have thought of this before. Maybe I can add it to the intro, or in the title? But I don't know Robin well enough to make hair jokes, and who am I to make hair jokes anyway? And what if Simon Pampena gets offended because he thinks he's 'The Super Perm' of maths?? And then neither of them ever guest appear again??... ugh, but it would have been so good. Oh well...) 12:29 "now!" (looks down. 'Darn it.') Комментарий от : @shanybiran468 |
