Cyclic Group C_10


The cyclic group C_(10) is the unique Abelian group of group order 10 (the other order-10 group being the non-Abelian D_5). Examples include the integers modulo 10 under addition (Z_(10)) and the modulo multiplication groups M_(11) and M_(22) (with no others). Like all cyclic groups, C_(10) is Abelian.

CyclicGroupC10CycleGraph

The cycle graph of C_(10) is shown above. The cycle index is

 Z(C_(10))=1/(10)x_1^(10)+1/(10)x_2^5+2/5x_5^2+2/5x_(10).
CyclicGroupC10Table

Its multiplication table is illustrated above.

The numbers of elements satisfying A^i=1 for i=1, 2, ..., 10 are 1, 2, 1, 2, 5, 2, 1, 2, 1, 10.

Because the group is Abelian, each element is in its own conjugacy class. There are four subgroups: {1}, {1,E}, {1,B,D,F,H}, and {1,A,B,C,D,E,F,G,H,I}. Because the group is Abelian, these are all normal. Since C_(10) has normal subgroups other than the trivial subgroup and the entire group, it is not a simple group.
