    León, Massé & Rivest (2006) show how to use the Cayley transform to generate and test matrices according to this criterion. We can also generate a uniform distribution in any dimension using the subgroup algorithm of Diaconis & Shahshahani (1987). This recursively exploits the nested dimensions group structure of SO(n), as follows.
