Query: Isomorphisms of Algebraic Number Fields   Let $\mathbb{Q}(\alpha)$ and $\mathbb{Q}(\beta)$ be algebraic number fields.
We describe a new method to find (if they exist) all isomorphisms,
$\mathbb{Q}(\beta) \rightarrow \mathbb{Q}(\alpha)$. The algorithm is
particularly efficient if the number of isomorphisms is one.
