I hadn’t heard of octonions for like  50 years.  Maybe work on imaginary
systems?  This is where dot products and cross products came from, more
tensor programming than constraint programming.  Have you considered
combining tensor and constraint programming?  Number systems with an
octonion base might be interesting.
