Abstract: Using Serre's proposed complement to Shih's Theorem, we obtain as a Galois group over for at least new primes . Assuming that rational elliptic curves with odd analytic rank have positive rank, we obtain Galois realizations for of the primes that were not covered by previous results; it would also suffice to assume a certain (plausible, and perhaps tractable) conjecture concerning class numbers of quadratic fields. The key issue is to understand rational points on Atkin-Lehner twists of . In an appendix, we explore the existence of local points on these curves.
