Finite subgroups of ${\mathrm{PGL}}_2(K)$ arising from configurations of skew lines in ${\mathbb{P}}_K^3$

Giuseppe Favacchio

We study finite groups arising from configurations of pairwise skew lines in ${\mathbb{P}}_K^3$. To such a configuration $L$ one associates a group $G_L\subset {\mathrm{PGL}}_2(K)$…
