Group of rational points on the unit circle is just "a"/"c" + "ib"/"c", where "i" is the imaginary unit. Conversely, if ("x", "y") is a rational point on the unit circle in the 1st quadrant of the coordinate system (i.e. "x" > 0, "y" > 0), then there exists a primitive right triangle with sides "xc", "yc", "c", with "c" being the least common multiple of "x" and "y" denominators. There is a correspondence between points ("x","y") in the "x"-"y" plane and points "x" + "iy" in the complex plane which will be used below, with ("a", "b") taken as equal to "a" + "ib". The set of
