I'm pretty sure the arms required to use proliferation make it unviable for tarcles.

Given that 50 is the cycle min for a solution without proliferation, I'm expecting there to be quite a pileup at 250.

My best result for 4 arms is 68 cycles (272 tarcles) and for 3 arms is 94 cycles (282 tarcles).

I feel like a 62 or lower for 4 arms (248 tarcles) might be possible, but I haven't been able to find it.
