Information on Result #587479

There is no linear OOA(3¹⁵, 30, F₃, 5, 10) (dual of [(30, 5), 135, 11]-NRT-code), because 3 times depth reduction would yield linear OOA(3¹⁵, 30, F₃, 2, 10) (dual of [(30, 2), 45, 11]-NRT-code), but

1 step m-reduction [i] would yield linear OA(3¹⁴, 30, F₃, 9) (dual of [30, 16, 10]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(3¹³, 19, F₃, 9) (dual of [19, 6, 10]-code), but
    - constructionÂ Y1 [i] would yield
      1. linear OA(3¹², 15, F₃, 9) (dual of [15, 3, 10]-code), but
        Griesmer bound [i]
      2. OA(3⁶, 19, S₃, 4), but
        the linear programming bound shows that MÂ â‰¥ 51975 / 67 > 3⁶ [i]
  2. linear OA(3¹⁶, 30, F₃, 11) (dual of [30, 14, 12]-code), but
    - discarding factors / shortening the dual code would yield linear OA(3¹⁶, 24, F₃, 11) (dual of [24, 8, 12]-code), but
      - â€œBSâ€ bound on codes from Brouwerâ€™s database [i]
