WebMar 28, 2024 · 1 Answer Sorted by: 2 Without loss of generality, let us take the left-to-right composition convention (i.e., assume that the permutation is acting from the right). Then simply observe that the permutation π = ( ( 1 2) ( 2 3) ⋯ ( n − 1 n)) maps each i to i − 1 mod n (so, 1 ↦ n = 0; 2 ↦ 1, …, n ↦ n − 1 ). Thus, π m maps each i to i − m mod n.
