Line 38: Consider the final transformation that you see in the second animation, and we compare this figure with the square base parallelepiped that contains it. We expect that the ratio between these figures becomes 1/2 to infinity. Performing calculations with Excel, you see that this is true. In addition~~, as has happened in the discussion at the link http://upload.wikimedia.org/wikipedia/commons/6/6c/Pubblicazione_english.pdf,~~ you encounter these other amazing results: <sub>n</sub> lim (Σ<sub>n</sub> n<sup>3</sup>)/(Σ<sub>n</sub> n).n<sup>2</sup> = 1/2
