TLDR
The Galois group of the generalized Laguerre polynomial F 2 n = e x x −2 n ( d 2 n ( e − x x 4 n )/ dx 2 n ) is the alternating group of degree 2 n, provided that F 2n is irreducible over the rationals as discussed by the authors.

Algebraic properties of a family of Generalized Laguerre Polynomials

Farshid Hajir
- 15 Jun 2004 - 
TL;DR: In this paper, the algebraic properties of generalized Laguerre polynomials for negative integral values of the parameter were studied for integers with constant n. The main tool is the theory of $p$-adic Newton Polygons.

On the Galois group of generalized Laguerre polynomials

TL;DR: In this article, a simple criterion for the Galois group of a polynomial to be "large" was formulated using the theory of Newton polygons, and it was shown that for a fixed ε ∈ Q − Z < 0, Filaseta and Lam have shown that the nth degree Generalized Laguerre Polynomial L (�) n (x) = P n=0 n+� n j � (−x) j /j! is irreducible for all large enough n.
