Description
The height of the tree associated to a permutation. A permutation can be mapped to a rooted tree with vertices {0,1,2,…,n} and root 0 in the following way. Entries of the permutations are inserted one after the other, each child is larger than its parent and the children are in strict order from left to right. Details of the construction are found in [1]. The statistic is given by the height of this tree. See also [[St000325]] for the width of this tree.

Description
The difference of lower and upper interactions. An ''upper interaction'' in a Dyck path is the occurrence of a factor 0k1k with k≄1 (see [[St000331]]), and a ''lower interaction'' is the occurrence of a factor 1k0k with k≄1. In both cases, 1 denotes an up-step 0 denotes a a down-step.
