| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{12} - 3456t^{10} - 43200t^{8} - 262656t^{6} - 775872t^{4} -
912384t^{2} - 110592\]
\[B(t) = 432t^{18} + 20736t^{16} + 425088t^{14} + 4838400t^{12} + 33229440t^{10}
+ 139677696t^{8} + 345461760t^{6} + 445243392t^{4} + 207028224t^{2} - 14155776\]
