| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{10} + 5184t^{8} - 84672t^{6} + 497664t^{4} - 442368t^{2}\]
\[B(t) = 432t^{15} - 31104t^{13} + 881280t^{11} - 12192768t^{9} + 80953344t^{7}
- 191102976t^{5} - 113246208t^{3}\]
