Damn, and I thought my 39 Cycles was impressive.

Yeah, I spent way too long trying to get it down to the theoretical minimum. Given it takes 16 cycles to produce all the atoms, and 3 cycles to produce, I think that I can probably be beaten on cost and area, but not cycles.

I moved the initial 3 elements to the opposite side. I think I require an extra arm though so couldn't match your 415 cost. Got it down to 430/19/39: https://i.imgur.com/jzEeKKr.gifv

I think if you make the pusher arm on the right on the second row rotate and do the work of the other pusher too, I think you can beat me.
Also, I know what you had to program for those 4 arms to the left. That's dedication.

I can't combine the pushers because it needs to grab at t+0 and drop at t+6, which means it can't get back to the start to grab again at t+8.
The 4 arms were actually easier than I expected. It's a straightforward group of 9 commands, repeated two more times with a delay of either 1 or 3 between each one. The extra 3 delay wasn't enough to cause problems with colliding arms.

This is what I meant.

I was inspired to try that design: 19 cycles, 345 cost.

Doh, I see, don't know why I thought the drop was at t+6 when t+5 works fine. Thanks!

Darn, I thought my 21-cycle solution was ideal haha. I made mine in 2 separate parts, one that builds it from two atoms, and one that builds it from 1 atom. I ended up with a couple solutions like these:

Didn't think about using all 3, with just sacrificing one grab-cycle for populating the 4th atom for the product.

I did the same thing for a while, sadly because you can't submit two products at the same time, building two can only get you as low as 20.

Holy shit. I was sweating blood to get a 38 cycle solution. I just couldnt imagine how did somebody get a sub 20 one. Im much more humble after seeing this.

I improved to 19 cycles / 335 cost: https://imgur.com/ko4qZo7

And even better: 315! https://imgur.com/F0spRFl

Dang! You posted before me. It seems we're basically using the same strategy, but at least my solution has a lower cost and area...

Stealing some of your ideas, I got the cost down to 415
