Yeah, so surprisingly, it's very decentralized.

I mean, there was about five, six people involved, and there was just a chat room, and we just all spoke.

We contributed ideas.

It was a very respectful environment.

If we had to write it, we haven't written a paper.

The problem was solved.

We haven't decided to write it.

actually formally make an official paper.

If we did, then we'd have to organize it a bit better.

But a lot of these crowdsourced solutions, they're just very spontaneous and very organic.

I actually like this mode of collaboration than sort of a more directed top-down thing where there's some principal investigator that sort of assigns tasks.

We can do that too, but sometimes we get it from the crowd, which is great.

Classic test for divisibility.

Ah, okay, yeah.

So you can phrase it in terms of a game.

Like, suppose you have a pile of coins, like 100 coins, and you arrange them in stacks.

Like, maybe you put 30 coins here, and then 50 coins here, and then 20 coins here.

So you arrange them in stacks, and some stacks are taller than others.

And then I get to pick some of the stacks and claim those coins for myself.

But I can only pick a sequence of stacks that's in increasing order or in decreasing order.
