Abstract : We study the representations of the commutator subgroup K {n} of the braid group B {n} into a finite group . This is done through a symbolic dynamical system. Some experimental results enable us to compute the number of subgroups of K {n} of a given finite index, and, as a by-product, to recover the well known fact that every representation of K {n} into S {r} , with n > r , must be trivial.
