Theory Update 36

A while back we played with Terence Tao's honeycomb pictures. Now we see that a one hexagon honeycomb is dual to the tetractys diagram for qutrits.
The Tao honeycomb represents three sets of eigenvalues for $3 \times 3$ matrices, with a zero sum. These eigenvalues are now indexed by tetractys edges, such as the edge $XXX$ goes to $XXY$.
