All products of operations in a group must themselves be members of that group. Prove this by showing the products of these multiplication operations in group
c4v. The c4 lies on the z-axis. You might need to use Cartesian axes or transformation
matrices to help you get the answers.
C1 4xE=_____
v(x,z)xC2=|
C3 4xv(x,z)=
