searching the database for statistics with the same generating function
Description
The global dimension of the incidence algebra of the lattice over the rational numbers.
Map
lattice of intervals
Description
The lattice of intervals of a permutation.
An interval of a permutation π is a possibly empty interval of values that appear in consecutive positions of π. The lattice of intervals of π has as elements the intervals of π, ordered by set inclusion.
Map
cycle-as-one-line notation
Description
Return the permutation obtained by concatenating the cycles of a permutation, each written with minimal element first, sorted by minimal element.
Map
Kreweras complement
Description
Sends the permutation πSn to the permutation π1c where c=(1,,n) is the long cycle.
