Construct codes and check distance
Build sparse parity-check matrices, then use exact ILP or randomized searches.

Build and inspect a code
Run from a configured repository checkout. These commands are not included in the two-binary native archive. list names available codes; show steane prints the selected code description. Distance-search results below are separate reference cases.

Exact results for small reference codes
Random-window searches report candidate upper bounds; they do not prove exact distance.
| Code | Method | Distance |
|---|---|---|
| Steane | Exact ILP | 3 |
| Toric d=4 | Exact ILP | 4 |
| Larger constructed codes | Random windows | Upper bound only |
