In this paper, we explicitly construct the Calabi composition of multipleaffine hyperspheres possibly including some points viewing as 0-dimensionalhypersheres. Then we compute all the basic affine invariants of the composedaffine hyperspheres, proving that the composed affine hypersphere is symmetricone if and only if each of its composing factors of positive dimension issymmetric.
