in 3+1-, 5+1-, and 9+1-dimensional spacetimes via the automorphisms of the fiber bundle base. In the latter two cases, singling out a preferred complex direction breaks each of these down to 3+1 dimensions [...] action of the equivariance group of the Hopf map leaves a residual SU(2)×U(1)/Z2 symmetry in the quaternionic case, and SU(3)×SU(2)×U(1)/Z6, the Standard Model gauge group, in the octonionic one. We speculate …
