All three files are essentially the same program, once as a .txt, twice as Jupyter notebooks. The .txt has the Iwasawa manifold as default parameter value, the others the families I+II of strongly non-nilpotent Lie algebras described in https://arxiv.org/abs/2011.09916. Use at your own risk and always double check the code or at least your results when you want to use this to prove something! In both files there is a question, if you find an example with the desired properties, let me know!
