WebOct 25, 2013 · 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.
