Model $\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is given by $y^2 = x^3 + A(t)x + B(t), \text{ where}$ $A(t) = -108t^{18} + 324t^{14} - 432t^{10} + 324t^{6} - 108t^{2}$ $B(t) = 432t^{27} - 1944t^{23} + 2592t^{19} - 2592t^{11} + 1944t^{7} - 432t^{3}$
Elliptic curve whose $2$-adic image is the subgroup $y^2 + xy = x^3 - x^2 - 4373667x - 2976605384$, with conductor $38025$
