The properties of the dihedral groups Dn with n ≥ 3 depend on whether n is even or odd. For example, the center of Dn consists only of the identity if n is odd, but if n is even the center has two elements, namely the identity and the element r (with Dn as a subgroup of O(2), this is inversion; since it is scalar multiplication by −1, it is clear that it commutes with any linear transformation). In the case of 2D isometries, this corresponds to adding inversion, giving rotations and mirrors i… Witrynagroups of order 6.] Solution. Suppose that G is an abelian group of order 8. By Lagrange’s theorem, the elements of G can have order 1, 2, 4, or 8. If G contains an element of order 8, then G is cyclic, generated by that element: G ˇC8. Suppose that G has no elements of order 8, but contains an element x of order 4. Let H =f1;x;x2;x3g
