Thanks just upgraded my phones unlock pattern ! 📱🔓👍
9:04 Knight's Tours almost _have_ to be more awesome. There's nothing surprising about a piece that moves 1 space at a time being able to visit every square. The weird movement of the Knight is what makes it interesting.

Exactly. It's the extra restriction on the Knight that makes it so much more impressive.

I love her comment on obsessions of drawing these mathematical objects! I'm a postdoc in theoretical physics, and I definitely questioned myself multiple times in the past, "Do I actually like physics, or do I just like drawing shapes?". It's really nice to see someone who emphasizes the same sentiment!!
I absolutely adore Ayliean MacDonald! I sometimes sit for hours making art by methods she's shown on Numberphile and her own channel.
0:38 looks like a Nepo v Dubov game 😂

chess, magic squares and beautiful art... lovely combination!
This is a visually beautiful video. Well done to the subject and the photographer.
"It's even cooler! If you look at the diagonals... April Fools!"
A knights tour on a Mobius Strip. That's it. That's the most perplexing thing I've ever seen.
Excited about the upcoming Parker Magic Tour

This episode was extra magical, thank you!
I know this wouldn't be a magic square, but the most obvious king's tour in the first place is the "snake path."
Some nice potential tattoo designs for Ayliean here! Love the 3D ones at the end!
Loved this.

Surely the room with those patterns on the walls was deliberately chosen. ❤ Ayliean
More than 25 years ago, I became somewhat entranced with knight's tours, and composed a few dozen of them that were very beautiful. I concentrated on the symmetrical ones, because I was looking for beauty. I even made a chessboard of knight's tours, which used 32 tours twice, mirroring each other. Each square of the chessboard was 2 inches, so the whole thing was 16 square inches. And it was a closed tour. I also made what I called modular tours, dividing the board into sections and then connecting the sections. It was loads of fun to play with something I had read about 50 years ago! 🐴
Matt Parker tries every year different method to calculate Pi, still he will be remembered for Parker Square 🤷♂️
On the sponsor screen before the video recommendations i heard Neil's beautiful voice. I miss his sequence videos so much. Hope he return some day
Anyone else notice that the 12x12 magic and semimagic knight's tours follow space filling curves? Super cool the fully magic one is a Hilbert curve, and that's why it translates up.
That rebelious squint smirk is my favorite
I bet these tours would look especially nice as Bezier curves.
Love that flash of the Parker Square
That's just fascinating.
Nice bit of -sunshade- fun shade thrown at Matt 1:32 LOL
3:05 I immediately thought of tiling in the pattern of a Hilbert curve
I chatted with Ayliean for 42 seconds in London last year. Highlight of my vacation.
Ayliean is a gem!
B2 looks great.
I've been watching since the original Parker Square. It was very funny to see it referenced again.
I think it's funny that you gave an example of a closed one before an open one, given that the closed one IS an open one 1 move before you close it.
1:30 catching strays 😂
7:10 was gonna say, that looks exactly like something you'd find in the Book of Kells, a very old church, or weaved into an aran jumper.
9:49 this I find very similar to that 'synchronously dancing bears' gif. Probably cuz they both have the same pace of movements and also the angle of view.
Now I want to make a belt and some border wallpaper with King's tour patterns.
Cool thing 😎 these Celtic patterns had some mathematical connection
The math speaks for itself.
Your makeup looks so nice! Also thanks for the cool math knowledge

Thank you ☺️✨
Are any of the magic, symmetric King's tours pan diagonally magic? Also, I find myself wondering about Queen's tours where you forbid King's moves and require alternation between Bishop and rook moves. Are any magic and symmetric... and how big can one make the smallest step and still complete a queen's tour? And what about tours using non-standard chess pieces or on a hex or triangular grid?
IDK, seems like king's tours & Celtic knots naturally divide a space with a line of connections. Sounds like a way to encrypt with complexity.
I have collected these patterns as knots
Just wanted to throw out there that these tours can be represented as a Hamiltonian path. Finding new tours could be done by changing which 2 vertexes connect to each other and then working to remake a new Hamiltonian path from that.
Ayliean and chess? Oh this will be an amazing episode!
Obviously you can start a closed tour from any square (you can start it at any point on the entire loop) but are there open tours that start at any given square? For a knight's tour, you obviously have to alternate colours, but if you pick any white square and any black square, is there always a tour that starts at one and ends at the other? I'm sure the answers are known, but they're still obvious questions to ask :)
It took a while but I eventually managed to successfully achieve a tour for every type of chess piece on a 1x1 board!
Big fan of the intersection of numberphile videos and puzzles from professor layton games that traumatised me as a kid. Eight queens next?

I think we’ve done that.
The patterns made by the magic king's tours make me think of knot theory. Also, I wonder if the fact that magic tours are possible on 8x8 with a king but not a knight has anything directly to do with the fact that a knight is strictly color-switching and a king isn't? Would you get the same results as the king with a piece with the same number of possible moves that is similarly divided between colorbound and color-switching, like a wazir+alfil?
Are there any underlying properties with the knot being made with this method?
Is there someplace online where we can view pictures of all the Knight's Tours and King's Tours?
I want those knight tour bracelets!
It's a Magical Chivalry Tour! (Roll up!)
I wish there was an option to see a pawn's tour... which promotes to a knight when it reaches the end of the board 😅
What are the RL applications to these tours besides it's pleasing to look at?

Nothing more for the moment I think Centuries ago mathematicians were playing with numbers developing what we call number theory today, ignoring that few centuries later we would use them for the security and cryptography of your credit card, or write the code source of your mobile phone or computer Soooooooo nothing for the moment I think, maybe one day it will have some And if not that's still beautiful enough to be published in my opinion

Chess is still unsolved. Specific board states of chess have been solved, but starting from White's turn 1, we're still mostly in the dark. Given there are more possible games of chess than there are atoms in the observable universe, chess is excellent for training computers and testing their limits. Research into topics like this could help us eventually solve chess, which would also result in solving problems using large or infinite numbers. If you can prove specific moves always leads to a win, you'd also be proving stuff about 10⁷⁸. It'd be like proving the last 10 digits of pi.
I personally like "dizzy king tour": where king not allowed make move in the same direction twice in the row.
How about a double bishops' tour?

This is mathematical wizardry 🧙
She shared the secret quite early on in the video! Is she sure we are her favorite kind of people????
2:54 In fact, there are no knight's tours _at all_ on a 4x4 board, let alone magic knight's tours. In general, there are clearly no knight's tours on 1xn or 2xn boards (except 1x1), and it turns out there are also no tours on 3x3, 3x5, 3x6, or 4x4 boards.
The magic knights tours seem to me to resemble a Hilbert curve shape. I wonder if this is a mathematical connection there. Both space filling curves?
Could we invent other moves? Could it work? Moves you don't find in chess, like 3-1. Fascinating as usual!

Nice house Ayliean has got! 😉
Parker Square spotted in the wild 😂
I wonder if they noticed the kings tours-like patterns on the wooden wall behind them…
Doesn't make a lot of difference in this context (though it definitely does in chess), but the bottom right square should be a light square if the board is set up correctly.

Only till it becomes a queen, and then it just zips around the rest of the board.
My tours with other pieces ran into problems when I got to bishops.

You should try a bishop's tour. I've been working on that, and it's going great! I'm almost half done, and no problems so far...
Do the diagonals really all have to look like that? Why not just have a big Snake-style squiggle? Just go horizontally over each row.
1×1 works.
