Map
to signed permutation
Description
The signed permutation with all signs positive.
Map
negatives to flag negatives
Description
A map sending the number of negative entries to the number of flag negative entries.
For a signed permutation $\pi\in\mathfrak H_n$, a flag negative entry is a positive entry followed by a negative entry in the sequence $\pi(-n),\dots,\pi(-1),\pi(1),\dots,\pi(n)$, see St001870The number of positive entries followed by a negative entry in a signed permutation..
This map leaves the underlying permutation intact, and uses Mp00268zeros to flag zeros on the sequence of signs.
