Sumset -> compression from the N=660 local maximum #1577 using the 6-point witness {0,1,6,7,15,55} modulo 63. The raw product {0,1,6,7,15,55}+63*A has 120 points modulo 41580. The same lift remains valid after compressing the N=660 factor to 655, giving modulus 63*655 = 41265 with all 120 points retained.
