"Classification of Topologically non-equivalent actions using generating vectors, a SAGE package
by Antonio Behn, Camila Muñoz and Anita M. Rojas.
"Completely decomposable Jacobian varieties in new genera"
by Jennifer Paulhus and Anita M. Rojas

The SAGE implementation of algorithms described in these papers is now available here.
