does anyone know what representation in group Oh = O x i , is the polar vector E a basis? E has components Ex, Ey, and Ez. How would I go about showing this? Thanks.

What group is that...?And who's $\vec{E}=\left(E_{x},E_{y},E_{z}\right)$...?

E is a polar vector, can be thought of to be the basis of a cube represented in Oh
