Really glorious flight today! Phenomenal that you encounter such friendly persons who will wave at you! probably speaks to the skill and smoothness of your approach/flying. and perhaps human nuances to your craft's flight. 🚁
I think I seen one of those spheres around the 3-minute mark. At some point I knew what I was doing when I was playing around with the 4x4 quaternion matrices. I made a sphere with three types of angles. I might even have the Maple file if I dig around for it.
yes, such graphs appear also in algebra like Cayley graphs of the quaternion group. I have experimented with primes in quaternions here arxiv.org/pdf/1606.05971 . The paper which was flashed around minute 3 is here ems.press/content/serial-article-files/45442
