`orthogonal_transformation`.
I chose that name 3 years ago. I agree it was not the best function name.
Your comments are very good. The reason that things are not clearly
written is that it is not clear enough in my head. Let me sleep this night
and I will come back on this tomorrow or later this week.
When `modpi=True`, I (think! I) want to quotient the result by the group
generated by the diagonal matrices of 1's and -1's with exactly two -1 on
the diagonal. Only, when the dimension is 3, I was able to generate
representative of the classes easily.
