GAP Package FPLSA

The FPLSA package uses the authors’ C program (version 4.0) that implements a Lie Todd-Coxeter method for converting finitely presented Lie algebras into isomorphic structure constant algebras. This is called via the GAP function IsomorphismSCTableAlgebra.

The current version of this package is version 1.2.7, released on 2025-08-29. For more information, please refer to the package manual. There is also a README file.
