It has discriminant  (and this polynomial can be used to define a global model ). It can be foundthrough the following procedure. First, we find some obvious torsion points by plugging in some numbers, which areIn addition, after trying some smaller pairs of integers, we find  is a point which is not obviously torsion.
This polynomial can be used to create a global model, and it's determined by finding specific points that are not obvious torsion points. This is done by first identifying some easily identifiable torsion points using numerical values, followed by searching for additional points that are not immediately apparent as torsion points.
