Explicit Schoen surfaces

Résumé

We give an explicit construction for the $4$-dimensional family of Schoen surfaces by computing equations for their canonical images, which are $40$-nodal complete intersections of a quadric and the Igusa quartic in $\mathbb P^4$. We then study a particularly interesting example, with $240$ automorphisms and maximal Picard number.
