In view of Remark 3.21, given $(B,\Delta,\mathscr{A})$ as in Example 3.16, a compactification $X(B_{0},\mathscr{A})\hookrightarrow(X,\omega)$ as above is uniquely determined up to symplectic conjugation by a choice of 24 formal power series in two variables:

$$\mathfrak{q}_{1},\ldots,\mathfrak{q}_{24}\in\mathbb{R}[\![x,y]\!]$$

corresponding to germs of focus-focus fibrations $\mathcal{F}_{1},\ldots\mathcal{F}_{24}$. In particular, there are infinitely many Lagrangian fibrations of a symplectic K3 surface, fibering over $(B,\Delta,\mathscr{A})$, which are all topologically conjugate but not symplectically conjugate.
