Commentary

Next sum-set iteration using the compressed N=287, |A|=14 local maximum discovered in the compression chain, paired with the dense N=145, |B|=10 local maximum. Positional product C=B_145+145*A_287 in Z/(145*287)Z gives 140 points. This follows the same compression -> sum-set strategy used in the N=104 run.
