| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -27t^{24} + 54t^{20} + 405t^{16} - 864t^{12} + 864t^{4} - 432\]
\[B(t) = 54t^{36} - 162t^{32} + 1782t^{28} - 4914t^{24} - 324t^{20} +
13932t^{16} - 12096t^{12} - 5184t^{8} + 10368t^{4} - 3456\]
