Template:Sets of 3-ary Boolean functions; prefect

Image set 3-ary Boolean functions in octeract matrix; prefects
The matrices numbered 0 ... 7 assign each 3-ary Boolean function to its prefect. The positions in the matrix denote the Boolean functions. The matrix number denotes the Walsh function, e.g. 7 for $(0,1,1,0,1,0,0,1)$ If the entry is red, the prefect is the negated Walsh function. The Boolean functions are identified either with their truth tables or their Zhegalkin indices.
