Denoting the space of linear isometries from [R.sup.k+1] to [R.sup.k+r] by Iso([R.sup.k+1], [R.sup.k+r]) and viewing it as a [GAMMA]-space via the action on [R.sup.k+1], this is equivalent to the existence of an equivariant continuous map

However, the Shilov boundary of [D.sub.5] given by [Q.sub.5] = [S.sup.4] x [RP.sup.1] is adequate enough to implement the action of SO(5) via isometries (rotations) on the internal symmetry space [S.sup.4] = SO(5)/ SO(4).
