Exceptional sequences of maximal length on some surfaces isogenous to a higher product

Let $S=(C\times D)\mathrm{/}G$ be a surface isogenous to a higher product of unmixed type with $p_g=q=0$, $G=(\mathbb{Z}\mathrm{/}2{)}^3$ or $(\mathbb{Z}\mathrm{/}2{)}^4$. We construct exceptional sequences of maximal length and quasiphantom categories on $S$.
