Producer Nicole here! We've been keeping this one under wraps for a while...

Well - we've shared it with the audience of Getting Triggy With It live shows - who were all obviously sworn to secrecy as well: the Stand-up Maths community has co-authored a paper with academics from MIT and JAIST to bring some brand new breaking maths news into the world!

We now know that there exists a net of area 106 which can fold into 3 different cuboids. This was something that mathematical institutions had failed to find out by themselves - but we emailed you fine folks (the people who love to see Matt code badly and then do it better yourselves) and a group of Stand-up Maths viewers managed to find it. Incredible.

Michael Tardibuono presented the paper at the Canadian Conference on Computational Geometry last week, and we can now share the video, and the paper with the masses. And as Patreons, you get it even earlier than everyone else too!

Enjoy the video and thank you for the support that keeps the channel running and lets us put real tangible new maths into the world.

There are some background quiet noises, plus a bit of music, when Matt talks about the matrix. Roughly 20:30 to 21:15. It seems to end with the cut from the PDF to Matt in the studio.

Chris Baker

So, where does this put your Erdős-Bacon Number?

Landon Kryger

@Christopher, we're getting an Erdős number of 3. Found a website that calculates this but our paper isn't in their database yet. We get it through Erik D. Demaine who's written 3 papers with Noga Alon, who wrote 4 papers with Paul Erdős.

Gregor Shapiro

I hear som music after "...matrix..." at 20:55

Michael Tardibuono

Oh crap! I only knew that Ryuhei had Erdos number of 2.

ViliamF

Yep. But there is some even quieter music before that. It's not easy to hear, but it's definitely there around the timestamps you and I mentioned.

Michael Tardibuono

It's a reference to another Stand-up maths video. "Can you trust an elegant conjecture?" EDIT: I can't hear any music before 20:55, but you might be right.

ViliamF

Ah, then I guess it should be louder. It's right on the edge of noticeable.
