note = "Funding Information: Numerous references are made in this paper to computations of the points on elliptic curves using a descent via an isogeny of degree two. Contrary to the overriding spirit of the paper, these computations are not included. They were carried out on a Sun 3/50 workstation which was paid for by a grant from the National Science Foundation. The software to compute these descents was written by the authors of this paper, based on mathematics which is explained carefully in [14]. Also, the equations of three-descents in Section 4 were made tractable while running MACSYMA on the same Sun workstation. Funding Information: by NSF grant DMS 86-00036; the second by NSF grant",
