Permutations, cycles and the pattern 2--13
The electronic journal of combinatorics, Tome 13 (2006)
We count the number of occurrences of restricted patterns of length 3 in permutations with respect to length and the number of cycles. The main tool is a bijection between permutations in standard cycle form and weighted Motzkin paths.
