Information on Result #547896

There is no linear OA(4¹⁸¹, 192, F₄, 136) (dual of [192, 11, 137]-code), because constructionÂ Y1 would yield

linear OA(4¹⁸⁰, 186, F₄, 136) (dual of [186, 6, 137]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(4¹⁷⁹, 183, F₄, 136) (dual of [183, 4, 137]-code), but
    - Griesmer bound [i]
  2. linear OA(4⁶, 186, F₄, 3) (dual of [186, 180, 4]-code or 186-cap in PG(5,4)), but
    - discarding factors / shortening the dual code would yield linear OA(4⁶, 160, F₄, 3) (dual of [160, 154, 4]-code or 160-cap in PG(5,4)), but
      - 1 times Hill recurrence [i] would yield linear OA(4⁵, 42, F₄, 3) (dual of [42, 37, 4]-code or 42-cap in PG(4,4)), but
        41 is the largest size of a cap in PG(4,Â 4) [i]
OA(4¹¹, 192, S₄, 6), but
- discarding factors would yield OA(4¹¹, 99, S₄, 6), but
  - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 4 278880 > 4¹¹ [i]
