Hey -- if anyone out there in TWW land are also working on this problem, but I'll throw it out.

Well, two questions I guess. First is Prove that a factor group of a cyclic group is cyclic. Obviously I know what a cyclic group is, but I don't know how to incorporate that into the factor group.

The second question is what is the order of 14 + <8> in the factor group Z_24 / <8>. I know that Z_24 / <8> becomes ... Z_6 (?), but I'm not sure how.

Thanks for any help you can throw my way..

too easy.

I'll help you on the first.

Look at how you proved the group axioms of G/N and think about what it means to be cyclic. Then apply the cyclic properties of G.

^ yep. Like he said remember that for a cyclic group we know how to explicitly write each and every element in terms of the generator raised to some power (0,1,2,3,...,g -1). For a cyclic group G of order g we knows:

G = {e,a,a^2,a^3,...A^g-1} with a^g=e

or if you like,

G = {0,a,2a,3a,...(g-1)a} with ga= 0

I suppose you'll want to think about additive groups in view of the problem to follow.
