Abstract
It is a well known fact that invariance under the orthogonal group and marginal independence uniquely characterizes the isotropic normal distribution. Here, a similar characterization is provided for the more general class of differentiable bounded Lp-spherically symmetric distributions: Every factorial distribution in this class is necessarily p-generalized normal.
