| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -891t^{8} - 3888t^{7} - 6264t^{6} - 2592t^{5} + 2808t^{4} - 5184t^{3} -
25056t^{2} - 31104t - 14256\]
\[B(t) = -10206t^{12} - 66096t^{11} - 169128t^{10} - 135648t^{9} + 382968t^{8} +
