Information on Result #583495

There is no linear OOA(3²⁰⁵, 203, F₃, 4, 141) (dual of [(203, 4), 607, 142]-NRT-code), because 2 times depth reduction would yield linear OOA(3²⁰⁵, 203, F₃, 2, 141) (dual of [(203, 2), 201, 142]-NRT-code), but

12 step m-reduction [i] would yield linear OA(3¹⁹³, 203, F₃, 129) (dual of [203, 10, 130]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(3¹⁹², 199, F₃, 129) (dual of [199, 7, 130]-code), but
    - residual code [i] would yield linear OA(3⁶³, 69, F₃, 43) (dual of [69, 6, 44]-code), but
      - â€œMaâ€ bound on codes from Brouwerâ€™s database [i]
  2. OA(3¹⁰, 203, S₃, 4), but
    - discarding factors would yield OA(3¹⁰, 172, S₃, 4), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 59169 > 3¹⁰ [i]

Mode: Bound (linear).
