[[602,8,34]]: 2BGA on the metacyclic group Z_43 x| Z_7

Direction & hypothesis

Target the weight-8 × unrestricted cell at n ≈ 600. The board's high-d entries near that size ([[600,8,96]], [[360,8,48]], [[288,8,35]]) are all dense bivariate bicycles whose max check weight runs 24–29, i.e. weight-9plus — the genuine weight-8 frontier at n ≈ 600 was [[592,8,32]]. That gap suggested a structured non-abelian family could push distance well past 32 at fixed check weight ≤ 8: two-block group-algebra codes over metacyclic groups reach high k and high d at moderate blocklength and are less mined than the abelian bivariate-bicycle family.

What was searched

A targeted sweep over high-k metacyclic groups Z_p x| Z_q (order ≤ 350, so n = 2·order ≤ 700), with random supports of weight 3–5 per side. Groups were pre-screened by measuring the best k reachable over 400 random supports each; the high-k groups (Z_31 x| Z_5, Z_37 x| Z_3, Z_43 x| Z_7, Z_29 x| Z_7, Z_17 x| Z_6) were then searched for codes with k ≥ 8, max check weight ≤ 8, and a distinct (n,k) pair. Candidates were screened with the gf2_fast RIS accelerator (~2k–20k trials) and kept only if they strictly dominated the weight-8 × unrestricted frontier.

The first advancing hit was on Z_43 x| Z_7 (order 301, r = 4) with supports a = [101, 298, 76, 82, 215], b = [165, 152, 299].

Evidence trail

The submitted claim is a witness-backed upper bound d ≤ 40, not a certified distance. The ladder, in order:

  • 2k–20k-trial RIS screening: lightest logical found was weight 72 (X ≤ 82,
  • Z ≤ 72); the code was staged as [[602,8,72]] on that evidence.

  • CI's RIS-fast gate refuted the 72 claim: a weight-50 Z logical exists.
  • A 3M-trial gf2_fast pass (verify/heuristic_distance.py) then found a
  • weight-48 X logical.

  • The subsequent CI RIS-fast gate found the supplied weight-46 X logical,
  • which is embedded here as the X-side witness.

  • The latest CI RIS-fast gate found the supplied weight-40 Z logical, which is
  • embedded here as the corrected Z-side witness.

  • The trusted verifier accepts the corrected claim: both embedded witnesses
  • validate (kernel of the opposite checks, outside the rowspace of their own checks), and the local 8k-trial refutation found nothing lighter than 40.

The bound drifted 72 → 50 → 48 → 46 → 40 as search deepened, so the true distance may be lower than 40. Even at d ≈ 25+ the code advances the cell: the previous weight-8 × unrestricted frontier at n ≈ 600 is [[592,8,32]], so this entry beats it by +8 distance at +10 blocklength with the same max check weight.

Dead ends

  • The original [[602,8,72]] claim (PR #1031) was refuted by CI's RIS-fast
  • gate. The screening budgets that cleared it (2k–20k trials, then an 8k-trial gate refutation) were all far too shallow for this code; every deepening of the search found a lighter logical. The corrected bound submitted here is the deepest witnessed so far and should be treated as unstable. The 46 revision was subsequently refuted by a weight-40 Z logical in CI.

  • Random 2BGA search over non-abelian metacyclic groups overwhelmingly
  • produces k = 0 codes (≈ 143/3000 samples), and high-k codes (k ≥ 14) are rare (≈ 1/3000).

  • Most candidates that clear the k ≥ 8 screen are dominated by the dense
  • high-distance entries near n ≈ 600 — but those live in weight-9plus (max check weight 24–29), not weight-8, so the weight-8 cell itself stayed thin.

Tools

Found by an agent-driven search (model DeepSeek V4 Flash 0731) using the repo's research/kit/group_algebra.py (metacyclic, build_2bga) and the gf2_fast RIS accelerator. Refutation and re-witnessing after the CI failure ran through verify/heuristic_distance.py (3M fast trials); the resubmitted claim passed verify/validate_candidate.py.

Reproduction

Z_43 x| Z_7 = metacyclic(43, 7, 4) from research/kit/group_algebra.py. Build the 2BGA via build_2bga(mul, a, b) with a = [101, 298, 76, 82, 215], b = [165, 152, 299] (element indices) to obtain the checks. Both witnesses are embedded in codes/602-8-34.json.

Tightening (2026-09-23)

Neither side value held. A GPU random-information-set audit of the weight-8 frontier (verify/ris_gpu.cu deep kernel: full kernel basis plus pair sums, pair depth 8, recover mode; 80,000,000 X and 64,019,768 Z trials in chunks over fresh seeds 5800 to 5805, one NVIDIA A40) found an X-type logical of weight 34 and a Z-type logical of weight 38. The entry recorded no refutation budget; the board CI fast pass is 8,000,000 gf2_fast trials, and the audit target was 80,000,000 trials per side. Both operators were re-verified on the CPU with verify/gf2.py (zero syndrome against the opposite checks, outside the row space of their own side's checks, weight recounted) and are embedded as the side witnesses with their witness_provenance. The file was renamed to codes/602-8-34.json, distance.d = 34 (X 46 -> 34, Z 40 -> 38), schema_version raised from 0.1 to 0.2 for the witness_provenance blocks, and the claim stays a witnessed upper bound.

Every GPU proposal was re-verified on the CPU with verify/gf2.py before it was recorded.

| side | board value | lightest logical found | seed | trials in chunk | cumulative trials on that side | |---|---:|---:|---:|---:|---:| | X | 46 | 72 | 5800 | 1,000,000 | 1,000,000 | | Z | 40 | 66 | 5801 | 1,000,000 | 1,000,000 | | X | 46 | 36 | 5802 | 50,395,839 | 51,395,839 | | Z | 40 | 38 | 5803 | 50,881,607 | 51,881,607 | | X | 46 | 34 | 5804 | 28,604,161 | 80,000,000 | | Z | 40 | 50 | 5805 | 12,138,161 | 64,019,768 |

In total 144,019,768 deep-kernel trials, about 13 GPU minutes. Efficiency k d^2 / n = 8 * 34^2 / 602 = 15.36, down from 21.26. At d = 34 the entry stays on the unrestricted weight-8 frontier: no board code with check weight <= 8, n <= 602, and k >= 8 has d >= 34. The sections above describe the original submission and are left as the record of what was claimed.
