| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{16} - 4320t^{14} - 72576t^{12} - 663552t^{10} - 3568320t^{8} -
11321856t^{6} - 19823616t^{4} - 15482880t^{2} - 1769472\]
\[B(t) = 432t^{24} + 25920t^{22} + 694656t^{20} + 10962432t^{18} +
