“…Example 2.1. Let π ∈ S 29,3 be the following permutation in cycle notation: Then f 3 (π ) = {(1, 2, 3) 3 , (4, 5, 6), (4), (4,6,5), (5), (6), (7,7,7), (8) 3 , (9) 2 , (9, 10, 10)}. The permutation π belongs to an equivalence class (7,7,7); (1, 2, 3) 3 , (4, 5, 6), (4, 6, 5), (9, 10, 10); (4), (5), (6), (9) (4,5,6), (4, 6, 5), (9, 10, 10), (4), (5), (6), (9) 2 .…”
