Information on Result #557984

There is no linear OOA(3²²⁰, 154, F₃, 2, 172) (dual of [(154, 2), 88, 173]-NRT-code), because 73 step m-reduction 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).
