My next video will be about trying to find a knot in the London Underground. Featuring: Sabetta, Henry, Vicki and Geoff.

https://youtu.be/Qp2LDpJo-Ng

This is an advanced release of the bonus video where we talk some maths and discuss the ‘rules’ for finding knots. Try to find your own!

Soon I will release the main video and make this bonus one public. Until then: please don’t leak what video is coming next!

But have you seen the 8 comments that “Arranging the Lily Pads” is set to Private?

Matt Parker

Fixed! Thanks. I uploaded it right before a bunch of international flights and totally missed the comments. Which is unlike me!

Gilad Teller

The bigger challenge would be to find a mobius railway line

Pavel Lishin

The lady with the bun looks very uncomfortable with all this nerdery.

Pavel Lishin

This... might be possible in New York, depending on how you define "side", since at some terminal stations trains can go on either the "left" or "right" side of the track...

Matt Parker

There are some great background facial expressions in the main video. I missed them at the time of filming but it’s pretty funny watching the footage back and keeping an eye on our fellow passengers.

A trefoil knot forms the edge of a Mobius loop, so we kinda did!

Vincent Zalzal

That disgusted look at 1:03 is priceless!

Are we limited to London or can we use our local networks instead ?

Matt Parker

Use any network! I figure there are plenty of other subway systems that are complex enough to contain a knot.
