ADITTYA CHAUDHURI (Jul 23 2021 at 21:36):In the note Lie 2-Algebras and the Geometry of Gerbes https://math.ucr.edu/home/baez/namboodiri/stevenson_maclane.pdf by Danny Stevenson, I came across the notion of "Higher Lie Schreier Theory". But this note had been written around 2006. I am interested to know the current status of Higher Lie Schreier Theory. It would be of great help if someone can provide some recent literature in this direction.
