Let O be the group of rotational symmetries of the cube (see figure of cube below left); we know it has order 24 (follows from the orbit-stabilizer theorem, see Chapter 1). (1). O contains rotations of order 2, 3 and 4. Give a brief description of these and determine how many there are in each conjugacy class. You will need to introduce some notation for this discussion, and a geometric discussion is sufficient: you do not need to prove the conjuga- cies. [Hint: there are 5 conjugacy classes of elements, one of which is the identity {I}.] (2). Suppose in general a finite group G acts on two sets X and Y. Let Z = X x Y, and consider the so-called diagonal action of G on Z given by g. (x, y) = (g.x, g.y). Write down Burnside's formula for the number of orbits of a G-action. Find Z8 in terms of X8 and Y%, explaining your answer carefully, and deduce an expression for the number of orbits for the G action on Z in terms of the actions on X and Y. (3). Consider now the action of 0 on V, the…

Check the information below and determine if it is not correct make correction as needed Group (LI ∘): The symmetries of the capital letter I consist of the identity transformation (no change), horizontal reflection (F1), vertical reflection (F2), and 180-degree rotation (R1). The group has four elements: {I, F1, F2, R1}. Group (F, ∘): The symmetries of the given shape consist of the following transformations: no change (I), 90-degree rotation counter-clockwise (R1), 180-degree rotation counter-clockwise (R2), and 270-degree rotation counter-clockwise (R3). The group has four elements: {I, R1, R2, R3}. To prove isomorphism between two groups, they must satisfy the following criteria: They have the same number of elements. There exists a bijective mapping (one-to-one correspondence) between their elements. The mapping preserves the group operation. In this case, the groups (LI ∘) and (F ∘) have the same number of elements, 4. We need to find a bijective mapping between these two…
