Abstract

In this chapter the structure of the orthogonal group is studied in more depth. In particular, we prove that every isometry in O(n) is the composition of at most n reflections about hyperplanes (for n ≥ 2, see Theorem 7.2.1). This important result is a special case of the “Cartan-Dieudonné theorem” (Cartan [29], Dieudonné [47]). We also prove that every rotation in SO(n) is the composition of at most n flips (for n ≥ 3).
