 Projective orthogonal group

The Projective Orthogonal Group, often denoted as \( P\text{O}(n) \), is a group that arises in the context of projective geometry and linear algebra. It is closely related to the orthogonal group and the projective space. Here's a breakdown of the definitions and concepts involved: 1. **Orthogonal Group**: The orthogonal group \( O(n) \) consists of all \( n \times n \) orthogonal matrices.
