How to show that a group is cyclic
WebJun 4, 2024 · Not every group is a cyclic group. Consider the symmetry group of an equilateral triangle S 3. The multiplication table for this group is F i g u r e 3.7. Solution The subgroups of S 3 are shown in F i g u r e 4.8. Notice that every subgroup is cyclic; however, no single element generates the entire group. F i g u r e 4.8. Subgroups of S 3 WebCyclic groups A group (G,·,e) is called cyclic if it is generated by a single element g. That is if every element of G is equal to gn = 8 >< >: gg...g(n times) if n>0 e if n =0 g 1g ...g1 ( n …

WebApr 3, 2024 · 1 Take a cyclic group Z_n with the order n. The elements are: Z_n = {1,2,...,n-1} For each of the elements, let us call them a, you test if a^x % n gives us all numbers in Z_n; x is here all numbers from 1 to n-1. If the element does generator our entire group, it … WebFor finite groups, an equivalent definition is that a solvable group is a group with a composition series all of whose factors are cyclic groups of prime order. This is equivalent because a finite abelian group has finite composition length, and every finite simple abelian group is cyclic of prime order. The Jordan–Hölder theorem guarantees ...
