DeltaMorphism(IntegerComposition)The lengths of the maximal runs of equal parts, left to right.

Typed signatures

Type	Package	Applies
(composition) -> composition	combinatorics	always

Domain: Combinatorial maps

Details

• Takes a IntegerComposition and returns a IntegerComposition — a typed map, so a wrong carrier is a type error rather than a wrong answer.
• FindStat's Mp00133. Lossy: the parts' values are forgotten. RunComposition is the same on a binary word.
