With straight diagonal lines.
Why are there gaps on either side of the upper-right square? Seems like shoving those closed (like the OP image) would allow a little more twist on the center squares.
I think this diagram is less accurate. The original picture doesn’t have that gap
You have a point. That’s obnoxious. I just wanted straight lines. I’ll see if I can find another.
there’s a gap on both, just in different places and you can get from one to the other just by sliding. The constraints are elsewhere so wouldn’t allow you to twist.
Oh, I see it now. That makes sense.
Oh so you’re telling me that my storage unit is actually incredibly well optimised for space efficiency?
Nice!
You may not like it but this is what peak performance looks like.
If there was a god, I’d imagine them designing the universe and giggling like an idiot when they made math.
Bees seeing this: “OK, screw it, we’re making hexagons!”
Fun fact: Bees actually make round holes, the hexagon shape forms as the wax dries.
But fear not, bees are still smart! Mfs can do math!
Not only can they do math, they can fully percieve time
come on now, let them cook, trust the process
Bestagons*
Texagons
4-dimensional bees make rhombic dodecahedrons
Here’s a much more elegant solution for 17
Can someone explain to me in layman’s terms why this is the most efficient way?
These categories of geometric problem are ridiculously difficult to find the definitive perfect solution for, which is exactly why people have been grinding on them for decades, and mathematicians can’t say any more than “it’s the best one found so far”
For this particular problem the diagram isn’t answering “the most efficient way to pack some particular square” but “what is the smallest square that can fit 17 unit-sized (1x1) squares inside it” - with the answer here being 4.675 unit length per side.
Trivially for 16 squares they would fit inside a grid of 4x4 perfectly, with four squares on each row, nice and tidy. To fit just one more square we could size the container up to 5x5, and it would remain nice and tidy, but there is then obviously a lot of empty space, which suggests the solution must be in-between. But if the solution is in between, then some squares must start going slanted to enable the outer square to reduce in size, as it is only by doing this we can utilise unfilled gaps to save space by poking the corners of other squares into them.
So, we can’t answer what the optimal solution exactly is, or prove none is better than this, but we can certainly demonstrate that the solution is going to be very ugly and messy.
Another similar (but less ugly) geometric problem is the moving sofa problem which has again seen small iterations over a long period of time.
Lol, the ambidextrous sofa. It’s a butt plug.
It’s also a great name for a cover band.
Butt rock covers of gospel songs perhaps?
All this should tell us is that we have a strong irrational preference for right angles being aligned with each other.
Thanks for the explanation
Any other configurations results in a larger enclosed square. This is the most optimal way to pack 17 squares that we’ve found

Bidwell, J. (1997)
Seriously?
It crams the most boxes into the given square. If you take the seven angled boxes out and put them back in an orderly fashion, I think you can fit six of them. The last one won’t fit. If you angle them, this is apparently the best solution.
What I wonder is if this has any practical applications.
Is this a hard limit we’ve proven or can we still keep trying?
We actually haven’t found a universal packing algorithm, so it’s on a case-by-case basis. This is the best we’ve found so far for this case (17 squares in a square).
Figuring out 1-4 must have been sooo tough
It’s kinda hilarious when the best formula only handles large numbers, not small. You’d think it would be the reverse, but sometimes it just isn’t (something about the law of large numbers making it easier to approximate good solution, in many cases)
I hate this so much
Do you know how inspiring documentaries describe maths are everywhere, telling us about the golden ratio in art and animal shells, and pi, and perfect circles and Euler’s number and natural growth, etc? Well, this, I can see it really happening in the world.
It’s important to note that while this seems counterintuitive, it’s only the most efficient because the small squares’ side length is not a perfect divisor of the large square’s.
What? No. The divisibility of the side lengths have nothing to do with this.
The problem is what’s the smallest square that can contain 17 identical squares. If there were 16 squares it would be simply 4x4.
He’s saying the same thing. Because it’s not an integer power of 2 you can’t have a integer square solution. Thus the densest packing puts some boxes diagonally.
And the next perfect divisor one that would hold all the ones in the OP pic would be 5x5. 25 > 17, last I checked.
the line of man is straight ; the line of god is crooked
stop quoting Nietzsche you fucking fools
Is this confirmed? Like yea the picture looks legit, but anybody do this with physical blocks or at least something other than ms paint?
It is confirmed. I don’t understand it very well, but I think this video is pretty decent at explaining it.
The proof is done with raw numbers and geometry so doing it with physical objects would be worse, even the MS paint is a bad way to present it but it’s easier on the eyes than just numbers.
Mathematicians would be very excited if you could find a better way to pack them such that they can be bigger.
So it’s not like there is no way to improve it. It’s just that we haven’t found it yet.
It is one prove more, why it is important to think literally out of the box. But too much people of this type
Not complete without the sounds
