Cycles hasn't been motivating to me this week, but I wanted to at least have a solve that's better at cycles than my cost solve. I want to construct the output using these 1/3 blocks, but the only way to get enough rotation on a 4 cycle puts an arm at the center which clearly can't output without breaking free. I can see a few ways someone might go about fixing that, but I'd probably just commit the pipeline to only make 2/3 chunks and finish the solution with a 1/3 chunk stolen from the other pipeline. The other pipeline would then only be merging thirds on an 8 cycle which is easier to deal with.
