1998_04_01_lindstrom: Lindström proved that a Sidon set of size about the square root of N inside the first N integers is asymptotically equidistributed among the residue classes of a fixed modulus, which answers Problem 154 yes for the sumset.

1998_08_14_kolountzakis: Kolountzakis proved an explicit bound on the discrepancy of a near-maximal Sidon set among residue classes, uniform in moduli growing with N, which strengthens Lindström's theorem and settles Problem 154.
