Abstract
A Kuribayashi quartic curve [Formula: see text] carries total sextactic points if and only if [Formula: see text] or [Formula: see text] is a zero of [Formula: see text], cf. [1] . In [2] , the authors describe the subgroup generated by the total sextactic points in the Jacobian of a Kuribayashi quartic curve when [Formula: see text] is a zero of [Formula: see text] In this paper, we describe this group when [Formula: see text]
