The arc chromatic number for Galois projective planes, affine planes and Euclidean gridsProvided a five-colouring of the 9×9 grid and independent verification programs, establishing χ_A(G9) = 5.
Public record
The public arXiv v2 names Haoxuan (Jason) Dong in the discussion of the open grid problem, records the construction as personal communication, and states that the authors independently verified the colouring.
Multiple Gauss Sums, Volume ISupplied the p = 3 case with proof; credited in §6.15 of Volume I, Version 7.
Public record
Zoltán Réti’s Multiple Gauss Sums Generated by Circulant Matrices, Volume I (Version 7, September 2026), credits Jason Dong in §6.15 on printed page 71 (PDF page 93): “The case p = 3 is due to Jason Dong, who supplied it, with proof”. The passage cites SeqFan correspondence from August 2026.
