Abstract

In the present article we construct new families of free and nearly free curves starting from a plane cubic curve CC and adding some of its hyperosculating conics. We present results that involve nodal cubic curves and the Fermat cubic. In addition, we provide new insight into the geometry of the 2727 hyperosculating conics of the Fermat cubic curve using well-chosen group actions.
