Again, omclone allows me to program these long tapeloops without tearing my hair out.

As I chip away at this primary, it rules out more and more layouts and input combinations which narrows my search.

What I like about this layout: small output-building area, no empty track hexes around the arm, full access to all but one hex
What I don't like about this layout: the calcifier placement makes moving the triplexed fire to the output assembly really tricky
