list st of Elliptic curves which for which ρE,2 is surjective mod 2 but not mod 4. I used a Heuristic approach to narrow down the list of elliptic curves for which $\rho_{2,E}$ is surjective mod 2 but not mod 4 or $\rho_{2,E}$ is surjective mod 4 but not mod.

The results of the above program for 2not4 curves is [[attachment:li4.sobj|li4.sobj]] [[attachment:2not4 output.txt|2not4 output.txt]]


I have verified the results of 2not4 list, using a Galois approach, which involves compute the order of the Gal(Q(E[4])/Q). The program I used is [[attachment:2not4galoisapproachv2.sage|2not4galoisapproachv2.sage]]


The results of the above program for 4not8 curves is [[attachment:li8.sobj|li8.sobj]]


I am working on verifying this result using the Galois approach.
