We give a complete classification of homomorphisms from the commutator subgroup of the braid group on n$n$ strands to the braid group on n$n$ strands when n$n$ is at least 7. In particular, we show that each non‐trivial homomorphism extends to an automorphism of the braid group on n$n$ strands. This answers four questions of Vladimir Lin. Our main new tool is the theory of totally symmetric sets.
