| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -442368t^{24} - 6856704t^{20} - 7050240t^{16} - 2681856t^{12} -
440640t^{8} - 26784t^{4} - 108\]
\[B(t) = -113246208t^{36} + 3482320896t^{32} + 10022289408t^{28} +
9314500608t^{24} + 4238770176t^{20} + 1059692544t^{16} + 145539072t^{12} +
