N2 - We consider a spherical antiprism. It is a convex polyhedron,with 2n vertices in the spherical space S 3. This polyhedron has a group,of symmetries S 2n generated by a mirror-rotational symmetry of order,2n, i.e. rotation to the angle π/n followed by a reflection. We establish,necessary and sufficient conditions for the existence of such polyhedron in,S 3. Then we find relations between its dihedral angles and edge lengths,in the form of cosine rules through a property of a spherical isosceles,trapezoid. Finally, we obtain an explicit integral formula for the volume,of a spherical antiprism in terms of the edge lengths
