Information on Result #577589

There is no linear OOA(9²⁹, 58, F₉, 3, 26) (dual of [(58, 3), 145, 27]-NRT-code), because 1 times depth reduction would yield linear OOA(9²⁹, 58, F₉, 2, 26) (dual of [(58, 2), 87, 27]-NRT-code), but

1 step m-reduction [i] would yield linear OA(9²⁸, 58, F₉, 25) (dual of [58, 30, 26]-code), but
- constructionÂ Y1 [i] would yield
  1. OA(9²⁷, 31, S₉, 25), but
    - the linear programming bound shows that MÂ â‰¥ 25644 034018 340666 323462 064529 / 377 > 9²⁷ [i]
  2. linear OA(9³⁰, 58, F₉, 27) (dual of [58, 28, 28]-code), but
    - discarding factors / shortening the dual code would yield linear OA(9³⁰, 39, F₉, 27) (dual of [39, 9, 28]-code), but
      - residual code [i] would yield OA(9³, 11, S₉, 3), but
        bound for OAs with index unity [i]

Mode: Bound (linear).
