How is the inheritance divided among one daughter, one full sister, and one full brother's son?

The daughter receives half, based on the Almighty's saying: "And if there is only one daughter, she receives half." The sister receives the remaining half by 'asabah (agnatic succession), as indicated by the hadith of Ibn Mas'ud in Al-Bukhari. The full brother's son receives nothing, as he is completely excluded by the sister.
