F0.<foo0>= NumberField(x^2 - 2) F1.<foo1>= F0.extension( polygen(F0)^2 - 5 ) L= F1.absolute_field("bar") L(foo0) ... TypeError: No compatible natural embeddings found for Number Field in bar with defining polynomial x^4 - 14*x^2 + 9 and Number Field in foo0 with defining polynomial x^2 - 2 So I cannot recover my square roots as elements of the field. I guess I could ask for the roots of X^2 - 2 over L. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
