Abstract

In this paper, we give an alternative construction of the Hölz design $D_{Hölz}(q)$, for $q\not\equiv 2$~mod~$3$. If $q\equiv 2$~mod~$3$, then our construction yields a $2-(q^3+1,q+1,\frac{q+4}{3})$-subdesign of the Hölz-design. The construction uses two hexagons embedded in the parabolic quadric $Q(6,q)$.
