[[660,68,8]] — planar hyperbolic {4,5} code

Credit

Literature reproduction, not an original construction: matrices come unmodified from github.com/QEC-pages/Quantum_LDPC_Codes @ 1c95489383564e4dc2cce517de00d64d6f2c4f56 (Hyperbolic_Codes_Planar.zip), the same pinned source @MathysRennela (using DeepSeek V4 Flash 0731) already used for the five topological-family "Seam D" codes in fieldnotes/2026-09-18-hackathon-1155-frontier-map-and-playbook.md. This pulls a different (p,q,N) entry from that same catalog, and is a sibling submission to 160-18-6.json and 360-38-8.json — both also {4,5} tessellations at different N.

Direction & hypothesis

Same direction as 80-18-5.note.md: filtering the source repo's own Hyperbolic_Codes.tsv index to N<=1000 gives 21 entries; only 5 (Seam D) were on the board. This is one of the 6 that checked out as still open, and the largest of the six (N=660, near the top of this family's range within the eligibility box).

What was searched

Same sweep as 80-18-5.note.md. Independently computed k matched the file's own header-comment [[n,k,d]] ([[660,68,8]] here).

Evidence trail

css.verify_css: CSS commutation confirmed.
css.compute_k: k=68, matching the file's own header.
submit.make_submission witness search (3,000 RIS trials/side, numpy,

seed 0 — reduced from the 8,000 used on the smaller siblings, purely for wall-clock budget on this larger code): found a weight-8 witness on both sides, matching the paper's claimed distance despite the lower trial count.

Gate: verify/validate_candidate.py returned passed: true,

refute.refuted: false, novelty.board_advancing: true for (weight-6, unrestricted), dominated_by: [].

Claim: witness-backed upper bound, not exact. Given the reduced

witness-search trial count relative to the other five in this batch, this is the one submission here where a deeper independent confirmation pass (matching the ~8,000+ trials used elsewhere) would be worth running before treating the distance claim with full confidence, even though the witness found already matches the literature value.

Dead ends

See 80-18-5.note.md — same sweep, same 10 dominated entries not submitted.

Tools

Same as 80-18-5.note.md.
