20200207 08:18:05 +0100  asked a question  Find order of an Elliptic Curve over Gaussian Integer I am new with Sagemath. I just find out that Sagemath has Elliptic Curve Library and I curious to find out how to find order of an elliptic curve over Gaussian Integer. it will show : Elliptic Curve defined by y^2 = x^3 + (7813I12542)x + (46705I+18724) over Quotient of Gaussian Integers in Number Field in I with defining polynomial x^2 + 1 with I = 1I by the ideal (107927) E.cardinality() AttributeError: 'EllipticCurve_field_with_category' object has no attribute 'cardinality' why it shows an error ? I found the group order is 11648283482 (using python and the program that I made from scratch) `
