The NumberField containing both embeddings should be larger. The morphisms also clearly show that something is going wrong:
sage: nf = NumberField(x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099, 'z', embedding=-1.18126721294295 + 3.02858651117832j) sage: nf2 = NumberField(x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099, 'z', embedding=-1.18126721294295 - 3.02858651117832j) sage: nf.composite_fields(nf2,both_maps = True) [(Number Field in z with defining polynomial x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099, Ring endomorphism of Number Field in z with defining polynomial x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099 Defn: z |--> z, Ring morphism: From: Number Field in z with defining polynomial x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099 To: Number Field in z with defining polynomial x^8 - 3*x^7 + 61/3*x^6 - 9*x^5 + 298*x^4 + 458*x^3 + 1875*x^2 + 4293*x + 3099 Defn: z |--> z, +Infinity)] I couldn't find a bug on trac for it. I think there should be one filed. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
