Abstract

In this article, we show that the minimal vectors of the extremal even unimodular lattices in R^{32} define T-avoiding universally optimal spherical codes for suitable sets T. Moreover, these codes are minimal T-avoiding spherical designs and maximal Tavoiding codes for appropriate choices of T.
