Is every finite abelian group is cyclic?
No, for instance the Klein group is finite and abelian but not cyclic. Even more groups can be found having this chariacteristic for instance Z9 x Z9 is abelian but not cyclic
Example of group is an abelian group?
The set of integers, under addition.
Is every cyclic group abelian?
Yes. Lets call the generator of the group z, then every element of the group can be written as zk for some k. Then the product of two elements is: zkzm=zk+m Notice though that then zmzk=zm+k=zk+m=zkzm, so the group is indeed abelian.
If d divides the order of a group does the group has a subgroup of order d?
The general answer is no. Consider A4={(1),(12)(34),(13)(24),(14)(23),(123),(124),(132),(134),(142),(143),(234),(243)}. The subgroups of A4 are: A4, , , , =, =, =, =, {(1),(12)(34),(13)(24),(14)(23)}, {(1)}. The order of A4 is 12, the order of , and is 2, the order of =, =, = and = is 3, the order of {(1),(12)(34),(13)(24),(14)(23)} is 4, and the order of is 1. Clearly there are no subgroups of order 6, but 6 definitely divides the order of A4. The statement is true for all finite abelian groups, and when d is a power of a prime (i.e., when d=pk for a prime p and a non-negative integer k).
What is the order of a group?
The order of a group is the same as its cardinality - i.e. the number of elements the set contains. The order of a particular element is the order of the (cyclic) group generated by that element - i.e. the order of the group {...a-4, a-3, a-2, a-1, e, a, a2, a3, a4...}. If these powers do not go on forever, it will have a finite order; otherwise the order will be infinite.
Is every abelian group is cyclic or not and why?
every abelian group is not cyclic. e.g, set of (Q,+) it is an abelian group but not cyclic.
Prove that a group of order three is abelian?
By LaGrange's Thm., the order of an element of a group must divide the order of the group. Since 3 is prime, up to isomorphism, the only group of order three is {1,x,x^2} where x^3=1. Note that this is a finite cyclic group. Since all cyclic groups are abelian, because they can be modeled by addition mod an integer, the group of order 3 is abelian.
Is the symmetry group of the square an abelian group?
Abelian meaning commutative. If the symmetry group of a square is commutative then it's an abelian group or else it's not.
Why is non abelion group smallest of six elements in mathematics?
The non-abelian group of smallest order (six elements) is the symmetric group S3. This group consists of all possible permutations of three elements, and it is non-abelian because the composition of permutations does not commute in general. It is the smallest non-abelian group because any group with fewer than six elements is either abelian or not a group.
What is the definition of an abelian group?
An abelian group is a group in which ab = ba for all members a and b of the group.
What does the term abelian mean?
The term abelian is most commonly encountered in group theory, where it refers to a specific type of group known as an abelian group. An abelian group, simply put, is a commutative group, meaning that when the group operation is applied to two elements of the group, the order of the elements doesn't matter.For example:Let G be a group with multiplication * or addition +. If, for any two elements a, b Є G, a*b = b*a or a + b = b + a, then we call the group abelian.There are other uses of the term abelian in other fields of math, and most of the time, the idea of commutativity is involved.The term is named after the mathematician, Niels Abel.
What is the number of groups of order 8 upto isomorphisms?
There are 5 groups of order 8 up to isomorphism. 3 abelian ones (C8, C4xC2, C2xC2xC2) and 2 non-abelian ones (dihedral group D8 and quaternion group Q)
What is an Abelian?

What is abelianization?
Abelianization is a homomorphism which transforms a group into an Abelian group.
