A comment on Geometric Algebra (2012). Parent comment
Its geometric product between motors is the equivalent of the 4x4 matrix product.
Although the basic computational complexity tells the story :
4x4 matrix product : 16 floats storage, 64 multiplies, 48 additions.
3D PGA versor product : 8 floats storage, 48 multiplies, 40 additions.
