Information on Result #2169730

There is no linear OA(8¹⁴⁹, 155, F₈, 131) (dual of [155, 6, 132]-code), because 3 times truncation would yield linear OA(8¹⁴⁶, 152, F₈, 128) (dual of [152, 6, 129]-code), but

constructionÂ Y1 [i] would yield
1. linear OA(8¹⁴⁵, 148, F₈, 128) (dual of [148, 3, 129]-code), but
  - Griesmer bound [i]
2. OA(8⁶, 152, S₈, 4), but
  - discarding factors would yield OA(8⁶, 104, S₈, 4), but
    - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 263173 > 8⁶ [i]

Mode: Bound (linear).
