Abstract
We discuss the construction and factorization pattern of a linear resolvent polynomial that is useful for computing Galois groups of degree 14 polynomials. As an application, we develop an algorithm for computing the Galois group of a degree 14 polynomial defined over the 7-adic numbers. This algorithm is of interest since it only makes use of the aforementioned linear resolvent, the polynomial’s discriminant, and subfield information of the polynomial’s stem field.
