A group G is a simple group if the only normal subgroups of G are G itself and {e}. In other words, G is simple if G has no non-trivial proper normal subgroups. Algebraists have proven (using more advanced techniques than ones we’ve discussed) that An is a simple group for n ≥ 5. Using this fact, prove that for n ≥ 5, An has no subgroup of order n!/4 . (This generalizes HW5,#3 as well as our counterexample from...
