Forced-Structure reduction shows no circulant graph on Z/99 satisfies more than 68.0% of constraints for Conway's 99-graph; verifiable bounds presented
Read the original at arxiv.org→arXiv:2608.11211v1 Announce Type: new Abstract: Conway's 99-graph problem asks whether a strongly regular graph with parameters $\mathrm{srg}(99,14,1,2)$ exists. We report a systematic, fully reproducible attack by...
