Positional sum-set construction starting from the N=104 record A={0,1,5,14,18,19,39,84} and the compressed N=287, |B|=14 local maximum: C=A+104B in Z/(104*287)Z. This alternates the sum-set and compression steps: the N=287 factor was compressed from the earlier N=301, |B|=14 witness, so the old 104*301=31304, 112-point product compresses to 104*287=29848 with all 112 points preserved.
