The one I came up with for 6 rectangles (divide the square down the middle on one axis, then into thirds on the other axis) I didn’t see in the 245 at the bottom of the article. I might have just skipped over it, but that one seems pretty trivial to me, so if they missed it, there must be some issue with their method. Edit: I think I misunderstood. They are interested in the number of unique ratios, not including different ways that rectangles of the same ratio could be drawn to fill a square. The pictures just show one example of how the rectangles of each ratio could fill a square. For my example, it looks like they have a square that is divided into the top third and bottom two-thirds, then the top third is divided in half, then the left half of that is divided into quarters. That’s another way of fitting six rectangles of ratio 1:1.5 into a square, besides the way I described above.
