Abstract

We describe the invariants of plane quartic curves -- nonhyperelliptic genus 3 curves in their canonical model -- as determined by Dixmier and Ohno, with application to the classification of curves with given structure. In particular, we determine modular equations for the strata in the moduli space \Me3\Me_3 of plane quartics which have at least seven hyperflexes, and obtain an computational characterization of curves in these strata.
