When a fan of a cult anime series wanted to watch its episodes in every possible order, they asked a question that had perplexed combinatorial mathematicians for years

Some snippets from the article:

Math solutions can be found in surprising places, including the dark realms of the Internet. In 2011 an anonymous poster on the now infamously controversial image board 4chan posed a mathematical puzzle about the cult classic anime series The Melancholy of Haruhi Suzumiya.

The first season of this anime series consists of 14 episodes that were designed so that you can watch them in any order you like. … At some point in a 2011 discussion of the series on 4chan, someone asked the minimum number of episodes they would have to watch to have seen it in every possible order.

one of the anonymous users made an estimate of the minimum amount of all episodes to watch with an approach that was previously unknown to mathematicians

Amazing coincidence that this was just published after the recent post in this community about alternate watch orders.

    No, the function is exponential so it would very quickly reach the bounds of modern computing limitations. The best analogy I can think of is folding a sheet of paper. With each fold the thickness doubles and it quickly becomes impossible to fold more than about 7 times. Now remember that this function doesn’t just double, it grows by many magnitudes each time.

      I can understand that. If we had values up to 7 or 8 identified exactly it may be possible to develop an equation for beyond, though. The smaller units are just too little for that though.
