Those choices are mostly driven by the end application where the algebra will be used, with its similarities (obviously, they are all algebras) and particularities. * &amp;quot;A brief introduction to Clifford algebra&amp;quot; - https://www.researchgate.net/profile/Giorgio_Vassallo/public... * &amp;quot;Doing euclidean plane geometry using projective geometric algebra&amp;quot; - https://arxiv.org/pdf/1501.06511.pdf * &amp;quot;Projective geometric algebra: A new framework for doing…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1901.05873/"&gt;Paper and discussion history&lt;/a&gt;.
