Summary

Description
only the kings

Each colored tesseract graph represents a 4-ary noble Boolean function.
They are representatives for each of the 44 factions, i.e. all 256 nobles can be derived from these by permutation.

The top left corner in each 2×2 matrix is a king, i.e. the function with the smallest Zhegalkin index in a royal faction.
The other three corners are its equivalents in the other quadrants. (Compare File:Noble 3-ary Boolean functions.svg.)

The black integers are the Zhegalkin indices of the Boolean functions.
The bigger beige integers tell the number of permutations in the beige rectangle.

The vertex colors illustrate the symmetry of the Boolean function. (This takes into account the whole tesseract, and not just its tetrahedral projection.)
