Versions: v3 (28 Nov 2024) prints the same value to its printed precision. Duplicate check: other rows on the instance: exact diagonalisation (Lanczos) -65.0524471206 (Sindermann et al., cond-mat/0605464); ConvNext (4,3,2)[1,1] with/without patching -65.047248 / -65.035152 (arXiv:2505.03466); none repeats this number or quotes this paper (the ConvNext rows are Nutakki et al.'s own results, the ED row is Sindermann et al.'s). Record note: the instance carries an exact row (ED -0.4517531050 per site, which this paper's caption also prints as -0.4517531), so by RULES.md 6 the exact row holds the record; this extrapolated row sits 3.1e-6 per site (4.5e-4 total) above it and is the closest challenger, not the record. sigma: the caption says only 'The Monte Carlo error due to finite sampling effects is on the last digit'; a table-wide 'error on the last digit' is not a sigma, so sigma stays null (rule of 2026-09-17).
