Two tools for cellular graph embeddings into closed surfaces given by rotation-system codes. general_codes.py enumerates all canonical codes with k edges, computes faces, Euler characteristic and genus, builds equivalence classes (rooted graphs, f-atoms, atoms) and saves the results as JSON. atoms_viewer.html is a sing...

This software generates, counts, and classifies codes of rotation systems of cell-embedded graphs in oriented surfaces with a fixed root vertex and a fixed oriented sector. For a given number kk of edges, a code is a finite sequence over the alphabet {0,1,…,k}. Each number 1,…,k occurs exactly twice, while 0 may occur...
