Non-Abelian number field
An algebraic number field with a non-Abelian Galois group over the field of rational numbers $ \mathbf Q $, or a field that is not normal over $ \mathbf Q $. Sometimes, instead of $ \mathbf Q $, one considers some other ground field $ k $ of algebraic numbers, and the term "non-Abelian" is understood to refer to the Galois group over $ k $.
