Galois lines for a canonical curve of genus 4, III: non-cyclic Galois lines

Shotaro Kato, Jiryo Komeda, Takeshi Takahashi

Let $C\subset {\mathbb{P}}^3$ be a canonical curve of genus $4$ over an algebraically closed field $k$ of characteristic zero. For a line $l\subset {\mathbb{P}}^3$, we consider the p…
