A solution to the ResearchNet assignment "Count", which appears in ResearchNet volume 4 issue 1.

This is a low-symbol solution, an entirely different animal from a low-cycle solution. You really need some lateral thinking to get a layout that's good for low-symbols, because while it's often possible to reduce an assignment to a set of simple steps, figuring out some way to get the job done with the least amount of arrows, flip-flops, grab/drops etc. is a real accomplishment.

Additionally, treating any product as a polymer always raises the difficulties of "when to do exception handling" and "how to detect when you're finished", which low-symbol certainly doesn't help with.

This is a pretty preliminary attempt here; I'm confident there's more to be done. I experimented with different sensor positions to detect specifically Carbon instead of Nitrogen, or eliminate the double-rotate in favor of a double-back on a single-rotate, but haven't gotten anywhere yet. It's also possible that putting the fuser under the hydrogen input to exploit the in-fuse lack-of-collision bug might help, although that means doing all the bonding off of the hydrogen input. Lots more room for experimentation.
