Non-Abelian Group of Order 4 and Order 3
Assuming that G is a non-abelian group with order 4 and order 3, we can deduce the following:
- The order of G is not 12, since the order of a group is the product of the orders of its cyclic subgroups, and G cannot have a cyclic subgroup of order 12.
- The order of G is not 6, since the only groups of order 6 are cyclic or isomorphic to S3, which are both abelian.
- Therefore, the only possibility is that the order of G is 4, and it has a subgroup of order 3.
Order of the Element in G
Based on the above observations, we cannot determine the order of the element in G. It could be finite or infinite, and there is no restriction on its form.
Option D is the Correct Answer
Hence, the correct answer is option D, which states that the order of the element in G need not be finite. This is because there are infinite groups that satisfy the given conditions, and they can have elements of any order, including infinite orders.
Conclusion
In conclusion, the order of the element in a non-abelian group G with order 4 and order 3 cannot be determined solely based on its properties. The answer could be finite or infinite, and there is no restriction on its form. Option D is the correct answer.
