We characterize that the image of the embedding of the Q-polynomial association scheme into the first eigenspace by primitive idempotent E 1 is a spherical t-design in terms of the Krein numbers. Furthermore, we show that the strengths of Pand Q-polynomial schemes as spherical designs are bounded by
## We given a new version of a theorem of Clay concerning the construction of BIB designs from Frobenius groups. In a recent paper [l] Clay describes a method of constructing BIB designs from Frobenius groups. Let G = N X @ be a Frobenius group with kernel N and complement @. With the same notatio
