  • There are 2 groups of order 6 (up to isomorphism) [duplicate]

    2 answers





Let $G$ be group with order $6$. Prove that either $G$ and $Bbb Z_{6}$ are isomorphic binary structure or $G$ and $S_{3}$ are isomorphic binary structure.




I know that for isomorphic binary structure, we define a function between groups and we should check homomorphism property and bijection. But I can not define a function between them. Please help me, if you have any good idea.

          Hint: Either your group has an element of order $6$ or not. If it has, then it is isomorphic to $mathbb{Z}_6$. Otherwise, which are the possible orders of elemets of $G$?

            Please start at least cursory efforts to look for duplicates of questions before you answer them. This is a rather standard question which you'd expect to have been asked on this site before, multiple times.
