Abstract
Modular Galois representations p : Gal(Q/Q) → GL 2 (F p ) with cyclotomic determinant arise from elliptic curves for small p. We show that p does not necessarily arise from an elliptic curve whose conductor is as small as possible outside p. For p = 3 this disproves a conjecture of Lario and Rio.
