Dihedral group

  1. Oct 14, 2005 #1
    Consider the dihedral group D/o, generated by x and y where o(x)=2 and o(y)=5
    What is the geometric significance of D/o?
    Which of G/<x> and G/<y> are well defined groups? Give reasons?

    Well, this sounds like homework... so what have you tried on this problem?

    BTW, it might help to define your symbols, so that we don't have to make guesses like:

    G is supposed to be D/o
    o(x) is supposed to be the order of the element x. (in G?)
    I actually have no idea what the o in D/o is...
