Explicitly, the projective orthogonal group is the quotient group PO(V) = O(V)/ZO(V) = O(V)/{I} Notions like continuity or connectedness make sense on them. It is located in the Oisans region of the French Alps. We know that for the special orthogonal group $$ \dim[SO(n)] =\frac{n(n-1)}{2} $$ So in the case of $SO(3)$ this is $$ \dim[SO(3)] =\frac{3(3-1)}{2} = 3 $$ Thus we need the adjoint representation to act on some vectors in some vector space $W \subset \mathbb{R}^3$.
