GridPyM: A Python module to handle grid diagrams

Agnese Barbensi and Daniele Celoria

Vol. 14 (2024), 31–39

Grid diagrams are a combinatorial version of classical link diagrams, widely used in theoretical, computational and applied knot theory. Motivated by questions from (bio)-physical knot theory, we introduce GridPyM, a Sage compatible Python module that handles grid diagrams. GridPyM focuses on generating and simplifying grids, and on modelling local transformations between them.
