Candidate proof of global extension of the six Table-2 colour patterns in Haugland's lattice
Year: 2026
Type: preprint
Abstract: Candidate proof that each of the six local edge-label patterns in Table 2 of Jan Kristian Haugland's arXiv:2608.04542v4 extends to a proper four-colouring of the full lattice L. The package includes a short proof note, two independently written exact verification programs, saved verification outputs, and SHA-256 checksums. This work does not claim to solve the Hadwiger–Nelson problem and has not been peer reviewed.
