Abstract:
We analyze properties of points of orders $2, 4$, and $8$ of a curve in the generalized Edwards form. Arithmetic for group operations with singular points of these curves is introduced. We propose a classification of curves in the Edwards form into three disjoint classes. Formulas for the number of curves of order $4n$ of different classes are obtained. Works of other authors are critically analyzed.
