Let C be the following curve in C2. 11664c13c22+536544c13c2+6170256c13+67068c12c22+1542564c12c2 +3085128c1c22−32393844c1c2+3085128c1+17739486c22+6941538c2=0. I checked that this curve has genus 1 using Sage. Therefore it is an elliptic curve. How to change coordinates such that the equation of this curve is of the form y2=f(x), where f is some polynomial. Thank you very much.
I tried to use the following codes in Sage.
R.<c1,c2> = QQ[]; Jacobian(11664c1^3c2^2 + 536544c1^3c2 + 6170256c1^3 + 67068c1^2c2^2 + 1542564c1^2c2 + 3085128c1c2^2 - 32393844c1c2 + 3085128c1 + 17739486c2^2 + 6941538c2)
But there is an error: NoEmbeddingError: not a sub-polytope of a reflexive polygon. How to find the normal form of the curve using Sage? Thank you very much.
