WebFor instance, we exam the primes 2,3,5,7 (or just 5,7) to see by cycle types that the galois group is the permutation group S3. For x^5+x^3+38*x^2-13*x+169 if one examines the primes up to 1000, then the splitting ratio (incorrectly) indicates A5 (ratio is 1/56), but if one looks at the degrees of the factors for just 2,3,5,7 then one gets S5 ...
