Only one further permutation arises when a full brother and a full sister are both present: a full brother, a full sister, and a paternal half-sister.
With this, the permutations number thirteen in all. Each of these thirteen cases then branches into two possibilities: either no fixed-share heir accompanies them, or such an heir is present. In the latter situation the fixed share may be a quarter, a sixth, a quarter together with a sixth, or a half. Thus, counting the first possibility (no fixed-share heir), we have five situations ⦗1⦘. Multiplying the five by the thirteen permutations yields sixty-five cases.
Case sixty-six occurs when, alongside the grandfather and the siblings, there are heirs entitled to one-half and one-sixth—for example: a daughter, a son’s daughter, the grandfather, a full sister, and a paternal sister.
Case sixty-seven is where heirs entitled to two-thirds accompany them; for instance: two daughters, the grandfather, a full sister, and a paternal sister.
Case sixty-eight is where heirs entitled to one-half and one-eighth accompany them; for example: a daughter, a wife, the grandfather, a full sister, and a paternal sister.
Can paternal siblings receive anything alongside full siblings in a readjusted division?
If among the full siblings there is a male, or there are two or more full sisters, nothing can remain for the paternal siblings. If there is only one full sister, she is made up to a full half; whatever remains after that passes to the paternal siblings.
