1/2P... Standard 1P was only slightly more I - around 107I or so... so not sure if worth it. Also - I'm still not totally convinced 90G is min gold but it seems it must be... at least with input and product in separate chambers!

Last minute total reprogramming of the left chamber managed to reduce the instructions from 101 to 99!

Worth noting that if you make 2 V's of 3 atoms each and connect them (similar to here via 1/2P) there seems to be no way to get the final bond on as the molecule is fully made and too big to twist all the way around to the side where the final bond needs to be made... at least the ways I tried it! If that way worked you'd save many instructions! Maybe I missed how?
