Enumeration of restricted permutation triples
The electronic journal of combinatorics, Tome 17 (2010)
The counting problem is investigated for the permutation triples of the first $n$ natural numbers with exactly $k$ occurrences of simultaneous "rises". Their recurrence relations and bivariate generating functions are established.
