http://math.stanford.edu/~akshay/math109/hw7.pdf 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.
