I guess this is only of interest to Mathematicians. Who else would care about its peculiarities?
The design consists of 14 different rectangles, all with the same area. The total area of the rectangles is equal to the total area of the background.
The afghan shown used Aran yarn. Using any other yarn would change the overall size. I used less than 100 metres for each rectangle. It is easy to calculate the amount of yarn needed because it s only one calculation that is needed for all the rectangles.
It is knitted from the long side. To avoid using more than one yarn at a time the tops and bottoms of the rectangles are knitted on, in the normal manner, as you go, but the sides of the rectangles are stitched. You can avoid this if you choose to do it intarsia-style.
