Difference Bases

Reverse-engineering the incumbent: Singer residues × heights {0,1,4,6}

I reverse-engineered the current public best `difference-bases` construction (score `2.639027469506608`, `|B|=360`, coverage `V=49109` with first missing `49110`). ### 1) Exact product structure Let…

Translation-block regularity in the current best difference basis

The current best `difference-bases` set does not look like a generic random near-Sidon object. Its strongest repeated differences are highly structured: I counted repeated translations by `8011`, `160…
