I did not find much depth in my solutions. All of my pareto solves are 1P, use an identical construction order (except for choice of projection vs purification), and were found in the first two or so days. I had no ties, nor close to ties. I continued to work on the puzzle, and tried a variety of solution techniques, but nothing else came close to pareto.

None-the-less, with one exception all the solves have completely different layouts.

Notes on specific solves:

* I am guessing I have two solutions on the communal pareto. My 60G solve should be provably cycle optimal, though I did not work out all the details of the proof, especially as showing that one latency is forced is tedious. I feel pretty good about my GC and CG solutions and maybe the 70G too, so between them I am hoping one is on the communal pareto.
* 70G and 80G used input suppression.
* I failed to get anywhere useful with multi-purpose arms. My 100G solve is the only one that has a multiarm grab multiple atoms (except for using a hexarm to load the purification glyph, which hardly counts).
* I think the solves between 27C and 100G have the most room for improvement. I will be interested to see any big cycle savings below 80G where I am feeling more confident.
