The grid for jigsaw pieces is normally not square, at least when I used to solve them. Something like 3:2 was more typical.
If you can vary the aspect ratio of the average piece between 2:3 and 3:2, or even just pick one of the extremes so you can rotate the grid, a lot more numbers are possible. 1000 can be an almost-square grid.
None of this has anything to do with the mathematical content which is really the point of the blog post, but it's where my mind went when he claimed certain numbers make for bad jigsaw sizes.
- beervirus 6y agoHe was allowing for aspect ratios all the way out to 2:1 (which seems too long and skinny to me).
- messe 6y agoThat's for the entire puzzle. I think they meant that the pieces themselves have closer to 3:2 aspect ratios.
- beervirus 6y agoOops, I misread.
- madcaptenor 6y agoOP here. It seems too long and skinny to me too! But I needed a nice place to draw the line. And I was originally doing the calculations in my head, so allowing up to only 1.5:1 or something would have made the arithmetic a bit harder.
