[curves] The genus 3 setting

[Schmidt, Jörn-Marc]

Dear Watson Ladd,

>However, there is a problem in that there may be an isogeny to a non-hyperelliptic curve.

I was looking just a bit into it: [1] presents such an isogeny for curves defined over fields with characteristic > 3.
Do you know of a similar result for smaller characteristics?

Best,

Jörn
