This paper gives a number of new spherical 4-designs, and presents numerical evidence that spherical 4-designs containing n points in k-dimensional space with k G 8 exist precisely for the following values of n and k: n even and 22 for k = 1; n 2 5 for k = 2; n = 12, 14, >I6 for k=3;n~2Ofork=4;n>29f
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
