Information on Result #2163821

There is no linear OA(4⁶⁴, 69, F₄, 49) (dual of [69, 5, 50]-code), because 1 times truncation would yield linear OA(4⁶³, 68, F₄, 48) (dual of [68, 5, 49]-code), but

constructionÂ Y1 [i] would yield
1. linear OA(4⁶², 65, F₄, 48) (dual of [65, 3, 49]-code), but
  - Griesmer bound [i]
2. linear OA(4⁵, 68, F₄, 3) (dual of [68, 63, 4]-code or 68-cap in PG(4,4)), but
  - discarding factors / shortening the dual code 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).
