Studies of Euler diagrams/dagoro

This 4-ary Boolean function has 7 of 16 true spots. (It is in . See matrix 9, row 7. is in matrix 23, row 3.)

With cell 0 it is a gap variant of inflated. Without it one of.

This function is in the same BEC. It is a filtrate of Studies_of_Euler_diagrams/gapspots/bazinga.

The relationship between the two is: (¬C, B, A, D) = (A, B, C, D)   or    (C, B, ¬A, D) = (A, B, C, D)

The different labels — A..D vs. B..E — do not matter for the conversion. One could also write: (¬D, C, B, E) = (B, C, D, E)
