Number fields with discriminant +-2^a 3^b Examples from three point covers, by David P. Roberts
In this paper we construct number fields ramified at 2 and 3 only,
with various moderate-sized non-solvable Galois groups.
We construct these fields by specializing three point covers,
some from the literature and some new here. The specialization
points come from solutions to a generalized Fermat equation.
We conclude with a specific suggestion for further research
and two general conjectures.
