circuits\] Let $M$ be a $q$-PMD induced by a $q$-Steiner system with blocks $\mathcal{B}$. Let $\mathcal{C}_{t+0}$ be the collection of all circuits of $M$ of dimension $(t+0)$. Then $\mathcal{C}_{t+0}$ are the blocks of a $t$-$(n,t+0,\lambda_{\mathcal{C}_{t+0}})$ design where $$\lambda_{\mathcal{C}_{t+0}}={\left[\begin{matrix} k-t \\ 0 \end{matrix} \right]_{q}}
