Subject hexagram
All positions are equal. It's just 6 intersecting lines, 4 intersections on each line. Which multiplies to 24 intersections but all counted twice. So 12 distinct intersections on which a Knight can appear. Inner or outer is all the same. Every spot always toggles 7 intersections, the spot itself + the 3 remaining spots on both lines.
