• Odd Order and Cyclic Groups

  As we just said, for the 2n elements (excluding e) in G, it has at most 2n cyclic subgroups, but if we check the subgroup generated by each element g, we find that g^(-1) generate the same cyclic subgroup.

• Cyclic Groups and Generators

  Each subgroup of G is also cyclic and if H is a subgroup of G, then H= with some integer k. Now H includes both a^42 and a^70 and we know that gcd(42,70)=14, thus H= is the smallest subgroup containing a^42 and a^70.
