For every alphabet size q not in {2,6}, a complete recursive [4,2,3]_q code exists.

Status is community- and machine-tracked and may lag. Verify independently before investing effort.

Statement

For every alphabet size q not in {2,6}, a complete recursive [4,2,3]_q code exists. Open residue: Only q=14 and q=18 remain after the source resolves q=26.

Assessment

Renown 1/5

Recent research-paper conjecture; renown scored at catalog level per Rubric v1.

Attackability 5/5

All orders are known except q=14 and q=18, turning the general conjecture into two finite construction problems.

Verification note

Produce a code/quasigroup table and verify the MDS and recursive-differentiability conditions exactly. — Current arXiv revision checked; source-stated open/partial. Independent literature and author confirmation still required. Editorially screened candidate; not independently certified open. Author confirmation pending.
