Homework Help: Computing the conjugacy classes of D20(dihedral group of order 20)

  1. Dec 3, 2008 #1
    1. The problem statement, all variables and given/known data
    To compute the conjugacy classes of D20

    2. Relevant equations
    The class equation, center of the group, group order, Lagrange's theorem that number of elements in conjugacy classes divides order of group

    3. The attempt at a solution
    i'm struggling to understand how to compute the conjugacy class of this group; i understand the definition of a conjugacy class but i just need some help on how to compute its conjugacy classes

    Details on the steps required to do this is very much appreciated
