dummy

This 3-ary Boolean function has 5 of 8 true spots.
The representations here are inflated with the argument C, so that it looks like a 4-ary Boolean function.

In this inflated form it has these relationshipts:

• It is inflated barogi without spots 8 and 12.
• Without spot 0 it becomes tinora.
• Without spots 0, 2, 6 it becomes dagoro
