ABSTRACT
What are the new features when the computation of J (r ) or M(po) is per
formed in the quaternions H or in the octonions G? Because the corresponding
sets live in M4 or M8, they cannot be displayed directly. In 1 ~ M4, a 30-
rendering of a 3D-section is often used in computer graphics [8]. No such option
exists in G ~ M8. We have therefore chosen to analyze all possible 2D-sections.
