| Model |
$\mathbb{P}^{1}$, a universal elliptic curve over an appropriate base is
given by
\[y^2 = x^3 + A(t)x + B(t), \text{ where}\]
\[A(t) = -108t^{18} - 5184t^{14} - 84672t^{10} - 497664t^{6} - 442368t^{2}\]
\[B(t) = 432t^{27} + 31104t^{23} + 881280t^{19} + 12192768t^{15} +
80953344t^{11} + 191102976t^{7} - 113246208t^{3}\]
