| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{32} - 1944t^{24} - 5292t^{16} - 5184t^{8} - 1728\]
\[B(t) = -432t^{48} + 11664t^{40} + 79056t^{32} + 190512t^{24} + 220320t^{16} +
124416t^{8} + 27648\]
