Determine the number of ways in which the faces of a regular dodecahedron (regular lZsided solid) can be colored with three colors. . Determine the number of ways in which the edges of a square can be colored with six colors so that no color is used on more than one edge. . Determine the number of ways in which the edges of a square can be colored with six colors with no restriction placed on the number of times a color can be used. . Determine the number of different llbead necklaces that can be made using two colors. Determine the number of ways in which the faces of a cube can be colored with three colors. Suppose a cake is cut into six identical pieces. How many ways can we color the cake with :1 colors assuming that each piece receives one color? How many ways can the ve points of a vepointed crown be painted if three colors of paint are available? Let G be a nite group and let sym(G) be the group of all permuta tions on G. For each g in G, let gbg denote the element of sym(G) de ned by g(x)= gxg'l for all x in 8G. Show that G acts on itself under the action g > qbg. Give an example 1n which the mapping g > gbg 1s not onetoone. 1. Find a Hamiltonian circuit in the digraph given in Example 7 dif- ferent from the one in Figure 30.3. 2.
