Edwards curvesAn Edwards curve is a curve in the plane. Specifically, the points on the Edwards curve are the points (x,y) satisfying the equation x^{2}+y^{2}=1+d*x^{2}y^{2}. Here are some examples of points on the Edwards curve for d=300:
and there are many more. Plotted over the reals this curve looks like this: Version: This is version 2014.12.27 of the edwardscurve.html web page.
