Map
toric promotion
Description
Toric promotion of a permutation.
Let σ∈Sn be a permutation and let
τi,j(σ)={σif |σ−1(i)−σ−1(j)|=1(i,j)∘σotherwise.
The toric promotion operator is the product τn,1τn−1,n…τ1,2.
This is the special case of toric promotion on graphs for the path graph. Its order is n−1.

Map
to increasing tree
Description
Sends a permutation to its associated increasing tree.
This tree is recursively obtained by sending the unique permutation of length 0 to the empty tree, and sending a permutation σ of length n≥1 to a root node with two subtrees L and R by splitting σ at the index σ−1(1), normalizing both sides again to permutations and sending the permutations on the left and on the right of σ−1(1) to the trees L and R, respectively.
