Information on Result #583080

There is no linear OOA(3¹⁸⁷, 154, F₃, 4, 139) (dual of [(154, 4), 429, 140]-NRT-code), because 2 times depth reduction would yield linear OOA(3¹⁸⁷, 154, F₃, 2, 139) (dual of [(154, 2), 121, 140]-NRT-code), but

40 step m-reduction [i] would yield linear OA(3¹⁴⁷, 154, F₃, 99) (dual of [154, 7, 100]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(3¹⁴⁶, 151, F₃, 99) (dual of [151, 5, 100]-code), but
    - Griesmer bound [i]
  2. linear OA(3⁷, 154, F₃, 3) (dual of [154, 147, 4]-code or 154-cap in PG(6,3)), but
    - discarding factors / shortening the dual code would yield linear OA(3⁷, 137, F₃, 3) (dual of [137, 130, 4]-code or 137-cap in PG(6,3)), but
      - a result by BarÃ¡t, Edel, Hill, and Storme [i]

Mode: Bound (linear).
