We reprove several results of Bannai concerning spherical t-designs and finite subgrourps of orthogonal groups. These include criteria in terms of harmonic representations of subgroups of O(n) for the corresponding orbits to be t-designs (t = 0, 1, 2, 3, ...) in Sn - 1. We also discuss a conjecture of Bannai, dating from 1984, according to which t is bounded independently of the dimension n (for n ≥ 3) for such designs.
