Description
The number of 2-rises of a permutation.
A 2-rise of a permutation π is an index i such that π(i)+2=π(i+1).
For 1-rises, or successions, see [[St000441]].

Description
The breadth of a permutation.
According to [1, Def.1.6], this is the minimal Manhattan distance between two ones in the permutation matrix of π: min
According to [1, Def.1.3], a permutation \pi is k-prolific, if the set of permutations obtained from \pi by deleting any k elements and standardising has maximal cardinality, i.e., \binom{n}{k}.
By [1, Thm.2.22], a permutation is k-prolific if and only if its breath is at least k+2.
By [1, Cor.4.3], the smallest permutations that are k-prolific have size \lceil k^2+2k+1\rceil, and by [1, Thm.4.4], there are k-prolific permutations of any size larger than this.
According to [2] the proportion of k-prolific permutations in the set of all permutations is asymptotically equal to \exp(-k^2-k).

Description
The number of indecomposable projective-injective modules in the algebra corresponding to a subset.
Let A_n=K[x]/(x^n).
We associate to a nonempty subset S of an (n-1)-set the module M_S, which is the direct sum of A_n-modules with indecomposable non-projective direct summands of dimension i when i is in S (note that such modules have vector space dimension at most n-1). Then the corresponding algebra associated to S is the stable endomorphism ring of M_S. We decode the subset as a binary word so that for example the subset S=\{1,3 \} of \{1,2,3 \} is decoded as 101.

Description
The number of minimal chains with small intervals between a binary word and the top element.
A valley in a binary word is a subsequence 01, or a trailing 0. A peak is a subsequence 10 or a trailing 1. Let P be the lattice on binary words of length n, where the covering elements of a word are obtained by replacing a valley with a peak. An interval [w_1, w_2] in P is small if w_2 is obtained from w_1 by replacing some valleys with peaks.
This statistic counts the number of chains w = w_1 < \dots < w_d = 1\dots 1 to the top element of minimal length.
For example, there are two such chains for the word 0110:
0110 < 1011 < 1101 < 1110 < 1111
and
0110 < 1010 < 1101 < 1110 < 1111.
