code

• R. Moschetti, F. Rota, L. Schaffler, The non-degeneracy invariant of Brandhorst and Shimada families of  Enriques surfaces

The package is available in its most recent form on GitHub. 

• R. Moschetti, F. Rota, L. Schaffler, A computational view on the non-degeneracy invariant for Enriques surfaces

The published package is available in its most recent form on GitHub. 

1. SageMath code cnd_finder (.py file). This version also includes the function CPhiFinder. The previous version of cnd_finder.py is available here;

2. Applications to examples (.zip archive of .py files);

3. Results of applications (.zip archive of .txt files).

Minimal working example: download and save the main module together with an example in the same folder. Then, run the example with SageMath. 

• A small SageMath script to play with Hirzebruch-Jung combinatorics is here (.ipynb) or here (.txt).
