1/ @EricLengyel
The reason I have been giving talks about geometric algebra at NASA recently is that they (rightfully) found the so-called “plane-based” formulation clunky and unpalatable. They rejected it in favor of the cleaner and more complete model I developed over the past few years.

Now, illuminate me on this. By plane-based you mean the vanilla algebra?

Oh I see, thanks. Tell me something, as to the anti products and anti vectors, where did you see that, originally? Reading no texts in geometric algebra anywhere lead me to that, except perhaps brief mentions in Chevaleys work.
5/ @EricLengyel
I developed antiproducts as part of my own research, starting around 2010, and PGA Illuminated is currently the only text that provides a complete treatment. The term “antivector” is just an alternate term for “pseudovector” or “(n-1)-vector” that is more consistent with the rest of the terminology used in the complete algebra.
