Let G=〈S〉 be a solvable subgroup of the symmetric group Sn given as input by the generator set S. We give a deterministic polynomial-time algorithm that computes an expanding generator set of size Õ(n2) for G. As a byproduct of our proof, we obtain a new explicit construction of ε-bias spaces of size Õ$(n{\rm poly}({\rm log} d))({{1}\over{\varepsilon}})^{O(1)}$ for the groups $\mathbb{Z}_d^n$.
