This is my proudest achievement yet. I burned through many, many layouts trying to find the one with the synergy of all hexarms. For me, this was extremely hard to find. I had many close calls and found the final 59I to 57I improvement at 1AM after about 20 hours of working with this metric. The only thing that stinks is arm 6 existing, not even being an hexarm. In another world, both products of the glyph of division go onto hexarm 7, potentially getting 53I. However, geometry denied me from entering that world.

I'm sure there is some tech I missed, but this should be a pretty good sane solution.
