    Plato, tutored by Theodorus, questioned why Theodorus stopped at √17. The reason is commonly believed to be that the √17 hypotenuse belongs to the last triangle that does not overlap the figure.pic.twitter.com/mfoT6KA4Da

        x = 4 + 1/(x + 4) => (multiply by x + 4) x^2 + 4x = 4x + 16 + 1 => x^2 = 17 Yup. Yes it does. Had to make sure...

        Not sire about other coibtries but design codes in New Zealand require uniform risers and goings as not to break rhythm of step causing injury. I like the idea tho!
