Information on Result #573649

There is no linear OOA(4¹⁷¹, 176, F₄, 3, 129) (dual of [(176, 3), 357, 130]-NRT-code), because 1 times depth reduction would yield linear OOA(4¹⁷¹, 176, F₄, 2, 129) (dual of [(176, 2), 181, 130]-NRT-code), but

1 step m-reduction [i] would yield linear OA(4¹⁷⁰, 176, F₄, 128) (dual of [176, 6, 129]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(4¹⁶⁹, 173, F₄, 128) (dual of [173, 4, 129]-code), but
    - Griesmer bound [i]
  2. linear OA(4⁶, 176, F₄, 3) (dual of [176, 170, 4]-code or 176-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]

Mode: Bound (linear).
