Effective computation of $\operatorname{SO}(3)$ and $\mathrm{O}(3)$ linear representation symmetry classes

Abstract

We propose a general algorithm to compute all the symmetry classes of any SO(3) or O(3) linear representation. This method relies on a binary operator between sets of conjugacy classes of closed subgroups, called the clips. We compute explicit tables for this operation, which allows us to definitively solve the problem.

isotropy classes, clips, linear representations, symmetry classes, tensorial representations
