Tileable throughput of 41 blue belts in a width of 20 tiles.
Initial compression and final de-compression left as an exercise to the reader. As a rule to de-compress any given row you'll want to pull the red and yellow belts out into one blue splitter, and then pull the blue underground out.
Can be stacked or padded with regular 2:1 braids to compress larger numbers of belts.
