| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -27t^{16} - 1080t^{14} - 18144t^{12} - 165888t^{10} - 892080t^{8} -
2830464t^{6} - 4955904t^{4} - 3870720t^{2} - 442368\]
\[B(t) = 54t^{24} + 3240t^{22} + 86832t^{20} + 1370304t^{18} + 14127696t^{16} +
