Conjugacy Classes of A4

[QUOTE="Dick, post: 4550926, member: 65100"] Random elements of A4 certainly isn't the best way. There are patterns here. 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. Now going from (123) to (132) takes one substitution, 2 into 3. So (23)(123)(23)=(132). But (23) is not in A4. Think "number of transpositions needed". [/QUOTE]
