Information on Result #557460

There is no linear OOA(3²⁰¹, 180, F₃, 2, 144) (dual of [(180, 2), 159, 145]-NRT-code), because 27 step m-reduction would yield linear OA(3¹⁷⁴, 180, F₃, 117) (dual of [180, 6, 118]-code), but

residual code [i] would yield linear OA(3⁵⁷, 62, F₃, 39) (dual of [62, 5, 40]-code), but
- residual code [i] would yield linear OA(3¹⁸, 22, F₃, 13) (dual of [22, 4, 14]-code), but
  - 1 times truncation [i] would yield linear OA(3¹⁷, 21, F₃, 12) (dual of [21, 4, 13]-code), but
    - â€œHNâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
