Popis: An asymptotic formula is established for the number of rational points of bounded anticanonical height which lie on a certain Zariski dense subset of the biprojective hypersurface $x_1y_1^2+\dots+x_4y_4^2=0$ in $\mathbb{P}^3\times\mathbb{P}^3$. This confirms the modified Manin conjecture for this variety, in which the removal of a thin set of rational points is allowed.
Comment: 60 pages; minor edits and added a reference to recent work of Lehmann and Tanimoto, where it is confirmed that the thin set we remove is the one predicted by the Lehmann-Sengupta-Tanimoto machinery
