Do the sons of the deceased brother inherit from their paternal aunt if she has no husband or children, and she has one full brother and four sisters?

The niece does not inherit, and the paternal nephew from the mother's side does not inherit. As for the full paternal nephew and the paternal nephew from the father's side, they are heirs, but they do not inherit from their paternal aunt if her full brother or half-brother from the father's side is present. The rule is that the 'asabah brother (full brother or half-brother from the father's side) completely excludes the paternal nephew, because the closer heir excludes the more distant one. Thus, the full brother excludes the half-brother from the father's side by consensus, and the half-brother from the father's side excludes the sons of the full brother, and the sons of the full brother exclude the sons of the half-brother from the father's side. The maternal brother is an heir by فرض (fixed share) and does not exclude the paternal nephew.
