Конечные группы симметрии в физике и как от них перейти к группам Ли

Интересная педагогическая статейка, возможно будет полезна для таких как я:))) Конечные-то группы я уже худо-бедно прохавал, а вот бесконечные пока еще не очень:))

Finite symmetry groups in physics: https://arxiv.org/abs/2102.02817
Robert A. Wilson
Finite symmetries abound in particle physics, from the weak doublets and generation triplets to the baryon octet and many others. These are usually studied by starting from a Lie group, and breaking the symmetry by choosing a particular copy of the Weyl group. I investigate the possibility of instead taking the finite symmetries as fundamental, and building the Lie groups from them by means of a group algebra construction.
