WebProof. (Sketch). First we know from the previous proposition that every permutation can be written as a product of transpositions, so the only problem is to prove that it is not possible to find two expressions for a given permutation, one using a product $s_1 s_2 \cdots s_{2m+1}$ of an odd number of transpositions and one using a product \(t_1 t_2 \cdots … WebMar 6, 2024 · Output: "231".
