This is one of 16 · 24 = 384 Euler diagrams of Boolean functions in the same NP equivalence class.
Each diagram has a mirrored equivalent describing the same function, so the EC contains only 192 functions.
Each diagram is denoted by a signed permutation of four elements.
The number values correspond to the colors of the four circles.
A negator flips the area from the concave to the convex side of the circle.
(The spiky side of the border denotes the inside of the set.)
