We embed the moduli space $Q$ of 5 points on the projective line ${{S}_{5}}$ -equivariantly into $\mathbb{P}\left( V \right)$ , where $V$ is the 6-dimensional irreducible module of the symmetric group ${{S}_{5}}$ . This module splits with respect to the icosahedral group ${{A}_{5}}$ into the two standard 3-dimensional representations. The resulting linear projections of $Q$ relate the action of ${{A}_{5}}$ on $Q$ to those on the regular icosahedron.
