Do all algebraic number fields arise from Eisenstein polynomials?

This question came up while going through the application of Eisenstein criterion: The $p$-th cyclotomic polynomial after changing the variable $x$ to $(x+1)$ satisfies Eisenstein criterion. That is ...

Lower Degree Elements in an Algebraic Number Field

Fix an algebraic integer $\alpha$ of degree $n$ such that the extension $K=\mathbf{Q}(\alpha)/\mathbf{Q}$ has intermediate fields. (We can assume $K$ is Galois with non-simple Galois group.) This ...

Primitive Elements for $S_n$ Galois Extensions?

This is an offshoot of my other question two days ago. How to apply Hilbert's Irreducibilty theorem? But it is of independent interest. Solutions of Inverse Galois Problem for a finite group ...
