-These are the angles from the table in the beginning of the article and their multiplies. For any $theta$ not in this set of solutions, the trace of $hat(B)^(-1) hat(R)_theta hat(B)$ is a non-integer, the matrix itself necessarily has non-integer entries and the $bold(n)'$ vector ends up with non-integer entries. This contradicts the premise, hence the restriction on possible $theta$'s.
