I
knew that the 16G table-conversion used by the 79G synth was a bit overblown...
Edit: One of the conversions shown can actually be done in 3G, bringing the total cost down to 67G:
Code: Select all
x = 65, y = 41, rule = B3/S23

Edit 2: Two days later, and I have
finally figured out an even cheaper table-conversion than before (8G per side, was 10G), resulting in a 63G synthesis of 46P4H1V0:
Code: Select all
x = 252, y = 26, rule = B3/S23

Edit 3: A spark_search run by Goldtiger has found a 3-glider loop-side table conversion (Obsoleting the 4G collision shown above), which results in a 61G synthesis:
