Description
The number of adjacencies of a permutation, zero appended. An adjacency is a descent of the form (e+1,e) in the word corresponding to the permutation in one-line notation. This statistic, adj0, counts adjacencies in the word with a zero appended. (adj0,des) and (fix,exc) are equidistributed, see [1].

Description
The number of anti-singletons of a set partition. An anti-singleton of a set partition S is an index i such that i and i+1 (considered cyclically) are both in the same block of S. For noncrossing set partitions, this is also the number of singletons of the image of S under the Kreweras complement.

Description
The number of fixed points of a parking function. If (a1,,an) is a parking function, a fixed point is an index i such that ai=i. It can be shown [1] that the generating function for parking functions with respect to this statistic is 1(n+1)2((q+n)n+1(q1)n+1).
