Schreier relator data for the original first-reduction period-one presentation.

In the low-cardinality tail case, the transported tail-period index set has cardinality two.

The original first-reduction canonical periods agree with the target period data.

The first-power kernel relator of the original period-one reduction lies in the normal closure of the source relators.

The tail-block word used for the one-head period-one target source map.

If the second-stage cleanup period data is not strict, one of the relevant periods is one.

Generator images for the map from the one-head period-one target presentation to the Schreier presentation.

The target signature obtained by replicating the tail in the double-period-one case.
