Determining all $(2, 3)$-torus structures of a symmetric plane curve
Pages: 341 – 349
In this paper, we describe all $(2, 3)$-torus structures of a highly symmetric $39$-cuspidal degree $12$ curve.
A direct computer-aided determination of these torus structures seems to be out of reach. We use various quotients by automorphisms to find torus structures. We use a height pairing argument to show that there are no further structures.
