In the same way -E and -X exist, it seems -N also exists. The patterns are mirrored or rotated or something. Will try to show something that makes sense.

Here's a view of (E,X,N) to the right, (E,X,-N) left. The glass blocks are where D-A=X is true, the red; false. Still figuring out what part of -N is "real".

Basically -N appears to be a mirror the same way -X is. A and B trade places and are inverted (multiplied by -1)

This is the start of my proof that -N is a mirror of -D or -X

Last picture was (E,D,N), this picture is (E,X,N). It's possible I have some flaw with how I'm generating this, but I think it's correct.

Confirming this holds true on -E as well.
