Computation of relative integral bases for algebraic number fields (Q1112873)

In the present paper the author computes relative discriminants and relative integral bases for the algebraic number fields \({\mathbb{Q}}(^ 6\sqrt{-3})/{\mathbb{Q}}\), \({\mathbb{Q}}(^ 6\sqrt{-3})/{\mathbb{Q}}(\sqrt{-3})\), \({\mathbb{Q}}(^ 6\sqrt{-3})/{\mathbb{Q}}(^ 3\sqrt{-3})\).
