Orthogonal group: Products, In Euclidean geometry & Topology

In mathematics, the orthogonal group in dimension n, denoted O(n), is the group of distance-preserving transformations of a Euclidean space of dimension n that preserve a fixed point (the origin), where the group operation is given by composing transformations. The orthogonal group is sometimes called the general orthogonal group, by analogy with the…
