Also, by 'Galois group' here I mean the group of the Galois closure of the covering. That means your more precise condition in the first display is indeed right in the case of a Galois covering.) | |

Sep 10, 2017 at 23:18 | comment | added | Vesselin Dimitrov | The more precise condition is that $p$ does not divide the order of the Galois group (which in turn divides $n!$). Did any of the places that gave this statement make a reference to the paper [Ramified primes in the field of moduli of branched coverings of curves, J. Algebra, 1989] by Sybilla Beckmann? It should be possible to read this from Corollary 5.7 at the very end of her paper. | |
