1. The problem statement, all variables and given/known data Show that every transposition (i,j)(1≤i≤j≤n) in Sn is expressible as a product of adjacent transpositions. Also express the transposition (1,9) as a product of adjacent transpositions. 2. Relevant equations none 3. The attempt at a solution Really struggling to even start the proof. Is the transposition (1,9)=(1,2)(2,3)(3,4)(4,5)(5,6)(6,7)(7,8)(8,9)?
