Official implementation of the ICML 2022 paper "Going Deeper into Permutation-Sensitive Graph Neural Networks"

Computational Group Theory in Scala. It's Scala permuted!

J scripts for calculating permutation groups

A GAP package for backtrack search in permutation groups with graphs

State-of-art algorithm for sorting by transpositions based on an algebraic approach with guarantee of approximation ratio of 1.375

Basic group theory algorithms for permutation groups, such as the creation of a stabilizer chain.

Computations with orbital graphs in GAP

Digitally separable permutations and tensor structures arising from the 27-card trick and repeated dealing on b^m positions.

Implementation of Schreier-Sims representation of finite groups

A custom Domain-Specific Language (DSL) and interpreter implemented in Python using Lark for the definition, algebraic manipulation, and programmatic analysis of finite permutations in cyclic notation. Features advanced lexical scoping, AST transformations, and dynamic braid visualizations via Matplotlib and NetworkX.
