WebAs other Answers point out, the definition of simple group is often stated as an equivalent property on normal subgroups, i.e. that there are only the group G itself and the trivial (identity) subgroup which are normal in G. These forms of definition are equivalent by the First Isomorphism Theorem (for groups). Share. frog and and apple island near oak island https://beyondwordswellness.com
