Description
The diagonal inversion number of an integer partition. The dinv of a partition is the number of cells c in the diagram of an integer partition λ for which arm(c)leg(c){0,1}. See also exercise 3.19 of [2]. This statistic is equidistributed with the length of the partition, see [3].

Description
The number of factors of a standard tableaux under concatenation. The concatenation of two standard Young tableaux T1 and T2 is obtained by adding the largest entry of T1 to each entry of T2, and then appending the rows of the result to T1, see [1, dfn 2.10]. This statistic returns the maximal number of standard tableaux such that their concatenation is the given tableau.
