Return to Abelian Group.
Let <math>G\{e,a,b,c\}</math> be an abelian group with <math>'e'</math> as an identity element. The order of the other elements are:
(A)2,2,3
(B)3,3,3
(C)2,2,4
(D)2,3,4
* | e | a | b | c |
---|---|---|---|---|
e | e | a | b | c |
a | a | e | b | b |
b | b | c | e | e |
c | c | b | e | a |
a and b have order 2(a * a = e and b * b = e). c has order 4 (since c * c = a and a * a = e)
