Abstract

We compile a complete list of isomorphism class representatives of curves of genus 6 over F2\mathbb{F}_2. We use explicit descriptions of canonical curves in each stratum of the Brill--Noether stratification of the moduli space M6\mathcal{M}_6, due to Mukai in the generic case. Our computed value of #M6(F2)\#\mathcal{M}_6(\mathbb{F}_2) agrees with the Lefschetz trace formula as recently computed by Bergstrom--Canning--Petersen--Schmitt.
