(b) For each of the symmetry operations in Dzh, identify a "complementary" operation, A, that combines with it to produce a net inversion operation, i. For example, for the identity operation, the complementary operation would simply be f. Once you have found these complementary operations, evaluate the result of i Å for each. Is there a pattern? (c) Construct transformation matrices for the symmetry operations i, C₂(z), and 8(xy), then evaluate the product of these matrices, i C₂(z) 8(xy). What is the symmetry operation represented by the product matrix?

Question
Only need B and C answer for A is provided
4. (a) Construct the group multiplication table for the Dan point group with operations
(identified within the xyz-axis system): E, C₂(x), C₂ (v), C₂(z), i, 8(xy), 8(xz),8(yz). You
will be asked to match various successive operations with the result that they produce on
the submission quiz. (Note that this is an Abelian group, so only half need be found.)
(b) For each of the symmetry operations in Dzh, identify a "complementary" operation, A,
that combines with it to produce a net inversion operation, i. For example, for the identity
operation, the complementary operation would simply be f. Once you have found these
complementary operations, evaluate the result of f A for each. Is there a pattern?
(c) Construct transformation matrices for the symmetry operations i, C₂(2), and (xy), then
evaluate the product of these matrices, i C₂(z) 8(xy). What is the symmetry operation
represented by the product matrix?

For a general vector (x, y, 2), the various operations have the following effect
0-0 0-C) 0-0)

From these results, we can deduce the effect of different successive sets of operations to
obtain the group multiplication shown here:
