and we take what is in their hands, as though no grandfather1 had ever been present.

When is the readjusted division applied?
The readjusted division is employed only when the full siblings are fewer than twice the grandfather and, after the fixed share has been assigned, more than one-quarter of the estate still remains. If the full siblings equal or exceed twice his number, there is no need for a readjusted division.

The outline of the readjusted division
The situations requiring readjustment number sixty-eight in all. They are confined to this figure because such cases demand that the full siblings be less than twice the grandfather, and the instances in which they fall short of that are reduced to five basic patterns:

1. Grandfather with one full sister.
2. Grandfather with two full sisters.
3. Grandfather with three full sisters.
4. Grandfather with one full brother.
5. Grandfather with one full brother and one full sister.

To each of these five patterns we then add paternal half-siblings, either bringing the total up to twice the grandfather or leaving it below that threshold.

With the single full sister, five permutations arise:

1. One full sister and one paternal sister.
2. One full sister and two paternal sisters.
3. One full sister and three paternal sisters.
4. One full sister and one paternal brother.
5. One full sister, one paternal brother, and one paternal sister.

With the two full sisters, three permutations arise:

1. Two full sisters and one paternal sister.
2. Two full sisters and two paternal sisters.
3. Two full sisters and one paternal brother.

With the single full brother, three permutations arise:

1. One full brother and one paternal sister.
2. One full brother and two paternal sisters.
3. One full brother and one paternal brother.

With the three full sisters, only one permutation exists:

1. Three full sisters and one paternal sister.
