Information on Result #550210

There is no linear OOA(5⁶², 68, F₅, 2, 50) (dual of [(68, 2), 74, 51]-NRT-code), because 1 times depth reduction would yield linear OA(5⁶², 68, F₅, 50) (dual of [68, 6, 51]-code), but

constructionÂ Y1 [i] would yield
1. linear OA(5⁶¹, 64, F₅, 50) (dual of [64, 3, 51]-code), but
  - Griesmer bound [i]
2. OA(5⁶, 68, S₅, 4), but
  - discarding factors would yield OA(5⁶, 45, S₅, 4), but
    - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 16021 > 5⁶ [i]

Mode: Bound (linear).
