<jats:title>Abstract</jats:title><jats:p>Inspired by a method of La Bretèche relying on some unique factorisation, we generalise work of Blomer, Brüdern and Salberger to prove Manin's conjecture in its strong form conjectured by Peyre for some infinite family of varieties of higher dimension. The varieties under consideration in this paper correspond to the singular projective varieties defined by the following equation<jats:disp-formula-group><jats:disp-formula><jats:alternatives><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" orientation="portrait" mime-subtype="gif" mimetype="image" position="float" xlink:type="simple" xlink:href="S030500411800004X_eqnU1" /><jats:tex-math>$$ x_1 y_2y_3\cdots y_n+x_2y_1y_3 \cdots y_n+ \cdots+x_n y_1 y_2 \cdots y_{n-1}=0 $$</jats:tex-math></jats:alternatives></jats:disp-formula></jats:disp-formula-group>in ℙ<jats:sub>ℚ</jats:sub><jats:sup>2<jats:italic>n</jats:italic>−1</jats:sup>for all<jats:italic>n</jats:italic>⩾ 3.
