Author’s abstract: We determine the size of spherical caps with centres at the points of a design that cover the whole sphere in Euclidean space with a given multiplicity. By projecting $$q$$-designs on one-dimensional subspaces, we obtain the nodes of a Chebyshev-type quadrature formula of the same precision $$q$$. For large values of $$q$$ we establish that the points of a minimal $$q$$-design are uniformly distributed on the sphere. We construct a weighted cubature formula on the sphere with the minimum number of nodes.
