Information on Result #555253

There is no linear OOA(2²⁶⁰, 269, F₂, 2, 131) (dual of [(269, 2), 278, 132]-NRT-code), because 1 step m-reduction would yield linear OA(2²⁵⁹, 269, F₂, 130) (dual of [269, 10, 131]-code), but

residual code [i] would yield linear OA(2¹²⁹, 138, F₂, 65) (dual of [138, 9, 66]-code), but
- 1 times truncation [i] would yield linear OA(2¹²⁸, 137, F₂, 64) (dual of [137, 9, 65]-code), but
  - residual code [i] would yield linear OA(2⁶⁴, 72, F₂, 32) (dual of [72, 8, 33]-code), but
    - adding a parity check bit [i] would yield linear OA(2⁶⁵, 73, F₂, 33) (dual of [73, 8, 34]-code), but
      - â€œBJVâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
