We consider 5-dimensional real vector bundles over S^4. Isomorphism classes of these are given by their clutching function in \pi_3(O_5)

Given that \pi_3(O_5)\to \pi_3(G_5) is isomorphic to the surjection

,

we see that the vector bundle \xi_k corresponding to 24k times the generator has a sphere bundle S(xik
