Try to compute the centralizer σ 12 34 in s4

WebTo find the centralizer of (12) in S4, we need to find all elements in S4 that commute with (12). Let's start by considering an arbitrary element σ in S4. We can write σ in cycle notation as a product of disjoint cycles. For example, if σ = (1 2)(3 4), then σ maps 1 to 2, 2 to 1, 3 to 4, and 4 to 3. Now, let's consider the product (12)σ. Webcentralizer Z S 4 ((12)(34)) is 24=3 = 8. In other words, the set of elements of S 4 commuting with (12)(34) is a subgroup Pof S 4 of order 8. Note that P contains H, since His abelian. The other 4 elements of Pcan be found by inspection: clearly (12) commutes with (12)(34), and then the remaining 4 elements of Pmust be the coset (12)H.

To go from (123) to (243) requires you change 1 into 2 and 2 into 4. So clearly (12) (24) (123) (24) (12)= (243). It involves two substitutions. And (12) (24) is in A4. You can get the others in the class the same pattern.
