 \p{This is also an experiment of using [Forester](https://www.jonmsterling.com/jms-005P.xml) for building [forests of evergreen notes](https://www.jonmsterling.com/tfmt-000V.xml). I wish to use it to organize many definitions and discussions about Spin groups. My hope to find these notes easier to reuse and refer to in blogs, papers, blueprints etc.}
