Question
Every cyclic group is also a:a.Generatorb.Abelian groupc.Non-abelian groupd.Trivial group
Solution
To determine whether every cyclic group is also a generator, abelian group, non-abelian group, or trivial group, we need to understand the definitions of these terms.
-
Generator: A generator of a group is an element that, when repeatedly combined with itself, can generate all the other elements of the group. In other words, every element of the group can be expressed as a power of the generator.
-
Abelian group: An abelian group is a group in which the order of the elements does not affect the result of the group operation. In other words, the group operation is commutative.
-
Non-abelian group: A non-abelian group is a group in which the order of the elements does affect the result of the group operation. In other words, the group operation is not commutative.
-
Trivial group: The trivial group is a group that consists of only one element, the identity element. It is denoted by {e}, where e is the identity element.
Now, let's analyze each option:
a. Generator: Every cyclic group is indeed a generator. By definition, a cyclic group is generated by a single element, called the generator. This generator can generate all the other elements of the group through repeated multiplication or exponentiation.
b. Abelian group: Not every cyclic group is an abelian group. While some cyclic groups are abelian (e.g., the group of integers under addition), there are also cyclic groups that are non-abelian (e.g., the group of rotations in a regular polygon).
c. Non-abelian group: As mentioned above, some cyclic groups can be non-abelian. Therefore, not every cyclic group is a non-abelian group.
d. Trivial group: A cyclic group cannot be a trivial group. By definition, a trivial group consists of only the identity element, whereas a cyclic group has at least two elements (the identity element and the generator).
In conclusion, every cyclic group is a generator, but not necessarily an abelian group, non-abelian group, or trivial group.
