Richie, I’m looking into the structures of enclosures and am comparing bar 9 1-6-b7-5 which you call a UA and bar 10 4-2-3-5 an enclosure. In the 16b75, the b7 is enclosed in a similar way that the 3 is enclosed in 4235. Why is it not an enclosure?
You are correct. There is a missing arrow in bar 9 1-6-b7-5. Everything else is correct. I will make sure it is added on the next update. Good observation…thanks!
