DualMajorIndexToIntertwining(SetPartition)The inverse of IntertwiningToDualMajorIndex: read the growth word as an intertwining word and rebuild the blocks.

Typed signatures

Type	Package	Applies
(set_partition) -> set_partition	combinatorics	always

Domain: Combinatorial maps

Details

• Takes a SetPartition and returns a SetPartition — a typed map, so a wrong carrier is a type error rather than a wrong answer.
• FindStat's Mp00174.
