This is false, the factor group need not be a subgroup of the original group.

comment What came first, the $\forall$ or the $\exists$?
Isn't E backwards the same as E upside-down regardless of the horizontal symmetry? I prefer to think of both as upside-down letters, as this is how they would have been produced on a printing press. You cannot make any letter backwards with the movable type, but you can place letters upside-down.
