Information on Result #555224

There is no linear OOA(2²⁵⁹, 248, F₂, 2, 141) (dual of [(248, 2), 237, 142]-NRT-code), because 21 step m-reduction would yield linear OA(2²³⁸, 248, F₂, 120) (dual of [248, 10, 121]-code), but

residual code [i] would yield linear OA(2¹¹⁸, 127, F₂, 60) (dual of [127, 9, 61]-code), but
- residual code [i] would yield linear OA(2⁵⁸, 66, F₂, 30) (dual of [66, 8, 31]-code), but
  - adding a parity check bit [i] would yield linear OA(2⁵⁹, 67, F₂, 31) (dual of [67, 8, 32]-code), but
    - â€œDHMâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
